  TELNET

+
+ * Move the telnet support's network select() loop go away and merge the code
+   into the main transfer loop. Until this is done, the multi interface won't
+   work for telnet.
+
  SSL
 
+ * If you really want to improve the SSL situation, you should probably have a
+   look at SSL cafile loading as well - quick traces look to me like these are
+   done on every request as well, when they should only be necessary once per
+   ssl context (or once per handle). Even better would be to support the SSL
+   CAdir option - instead of loading all of the root CA certs for every
+   request, this option allows you to only read the CA chain that is actually
+   required (into the cache)...
+
  * Add an interface to libcurl that enables "session IDs" to get
    exported/imported. Cris Bailiff said: "OpenSSL has functions which can
    serialise the current SSL state to a buffer of your choice, and
    recover/reset the state from such a buffer at a later date - this is used
-   by mod_ssl for apache to implement and SSL session ID cache"
+   by mod_ssl for apache to implement and SSL session ID cache". This whole

+
+ * OpenSSL supports a callback for customised verification of the peer
+   certificate, but this doesn't seem to be exposed in the libcurl APIs. Could
+   it be? There's so much that could be done if it were! (brought by Chris
+   Clark)
 
  * Make curl's SSL layer option capable of using other free SSL libraries.

+
+PROGRAMMING WITH LIBCURL
+
+About this Document
+
+ This document will attempt to describe the general principle and some basic
+ approaches to consider when programming with libcurl. The text will focus
+ mainly on the C interface but might apply fairly well on other interfaces as
+ well as they usually follow the C one pretty closely.
+
+ This document will refer to 'the user' as the person writing the source code
+ that uses libcurl. That would probably be you or someone in your position.
+ What will be generally refered to as 'the program' will be the collected
+ source code that you write that is using libcurl for transfers. The program
+ is outside libcurl and libcurl is outside of the program.
+
+ To get the more details on all options and functions described herein, please
+ refer to their respective man pages.
+
+Building
+
+ There are many different ways to build C programs. This chapter will assume a
+ unix-style build process. If you use a different build system, you can still
+ read this to get general information that may apply to your environment as
+ well.
+
+  Compiling the Program
+
+    Your compiler needs to know where the libcurl headers are
+    located. Therefore you must set your compiler's include path to point to
+    the directory where you installed them. The 'curl-config'[3] tool can be
+    used to get this information:
+
+        $ curl-config --cflags
+
+  Linking the Program with libcurl
+
+    When having compiled the program, you need to link your object files to
+    create a single executable. For that to succeed, you need to link with
+    libcurl and possibly also with other libraries that libcurl itself depends
+    on. Like OpenSSL librararies, but even some standard OS libraries may be
+    needed on the command line. To figure out which flags to use, once again
+    the 'curl-config' tool comes to the rescue:
+
+        $ curl-config --libs
+
+  SSL or Not
+
+    libcurl can be built and customized in many ways. One of the things that
+    varies from different libraries and builds is the support for SSL-based
+    transfers, like HTTPS and FTPS. If OpenSSL was detected properly at
+    build-time, libcurl will be built with SSL support. To figure out if an
+    installed libcurl has been built with SSL support enabled, use
+    'curl-config' like this:
+
+        $ curl-config --feature
+
+    And if SSL is supported, the keyword 'SSL' will be written to stdout,
+    possibly together with a few other features that can be on and off on
+    different libcurls.
+
+
+Portable Code in a Portable World
+
+ The people behind libcurl have put a considerable effort to make libcurl work
+ on a large amount of different operating systems and environments.
+
+ You program libcurl the same way on all platforms that libcurl runs on. There
+ are only very few minor considerations that differs. If you just make sure to
+ write your code portable enough, you may very well create yourself a very
+ portable program. libcurl shouldn't stop you from that.
+
+
+Global Preparation
+
+ The program must initialize some of the libcurl functionality globally. That
+ means it should be done exactly once, no matter how many times you intend to
+ use the library. Once for your program's entire life time. This is done using
+
+    curl_global_init()
+
+ and it takes one parameter which is a bit pattern that tells libcurl what to
+ intialize. Using CURL_GLOBAL_ALL will make it initialize all known internal
+ sub modules, and might be a good default option. The current two bits that
+ are specified are:
+
+  CURL_GLOBAL_WIN32 which only does anything on Windows machines. When used on
+  a Windows machine, it'll make libcurl intialize the win32 socket
+  stuff. Without having that initialized properly, your program cannot use
+  sockets properly. You should only do this once for each application, so if
+  your program already does this or of another library in use does it, you
+  should not tell libcurl to do this as well.
+
+  CURL_GLOBAL_SSL which only does anything on libcurls compiled and built
+  SSL-enabled. On these systems, this will make libcurl init OpenSSL properly
+  for this application. This is only needed to do once for each application so
+  if your program or another library already does this, this bit should not be
+  needed.
+
+ libcurl has a default protection mechanism that detects if curl_global_init()
+ hasn't been called by the time curl_easy_perform() is called and if that is
+ the case, libcurl runs the function itself with a guessed bit pattern. Please
+ note that depending solely on this is not considered nice nor very good.
+
+ When the program no longer uses libcurl, it should call
+ curl_global_cleanup(), which is the opposite of the init call. It will then
+ do the reversed operations to cleanup the resources the curl_global_init()
+ call initialized.
+
+ Repeated calls to curl_global_init() and curl_global_cleanup() should be
+ avoided. They should only be called once each.
+
+Handle the Easy libcurl
+
+ libcurl version 7 is oriented around the so called easy interface. All
+ operations in the easy interface are prefixed with 'curl_easy'.
+
+ Future libcurls will also offer the multi interface. More about that
+ interface, what it is targeted for and how to use it is still only debated on
+ the libcurl mailing list and developer web pages. Join up to discuss and
+ figure out!
+
+ To use the easy interface, you must first create yourself an easy handle. You
+ need one handle for each easy session you want to perform. Basicly, you
+ should use one handle for every thread you plan to use for transferring. You
+ must never share the same handle in multiple threads.
+
+ Get an easy handle with
+
+    easyhandle = curl_easy_init();
+
+ It returns an easy handle. Using that you proceed to the next step: setting
+ up your preferred actions. A handle is just a logic entity for the upcoming
+ transfer or series of transfers.
+
+ You set properties and options for this handle using curl_easy_setopt(). They
+ control how the subsequent transfer or transfers will be made. Options remain
+ set in the handle until set again to something different. Alas, multiple
+ requests using the same handle will use the same options.
+
+ Many of the informationals you set in libcurl are "strings", pointers to data
+ terminated with a zero byte. Keep in mind that when you set strings with
+ curl_easy_setopt(), libcurl will not copy the data. It will merely point to
+ the data. You MUST make sure that the data remains available for libcurl to
+ use until finished or until you use the same option again to point to
+ something else.
+
+ One of the most basic properties to set in the handle is the URL. You set
+ your preferred URL to transfer with CURLOPT_URL in a manner similar to:
+
+    curl_easy_setopt(easyhandle, CURLOPT_URL, "http://curl.haxx.se/");
+
+ Let's assume for a while that you want to receive data as the URL indentifies
+ a remote resource you want to get here. Since you write a sort of application
+ that needs this transfer, I assume that you would like to get the data passed
+ to you directly instead of simply getting it passed to stdout. So, you write
+ your own function that matches this prototype:
+
+    size_t write_data(void *buffer, size_t size, size_t nmemb, void *userp);
+
+ You tell libcurl to pass all data to this function by issuing a function
+ similar to this:
+
+    curl_easy_setopt(easyhandle, CURLOPT_WRITEFUNCTION, write_data);
+
+ You can control what data your function get in the forth argument by setting
+ another property:
+
+    curl_easy_setopt(easyhandle, CURLOPT_FILE, &internal_struct);
+
+ Using that property, you can easily pass local data between your application
+ and the function that gets invoked by libcurl. libcurl itself won't touch the
+ data you pass with CURLOPT_FILE.
+
+ libcurl offers its own default internal callback that'll take care of the
+ data if you don't set the callback with CURLOPT_WRITEFUNCTION. It will then
+ simply output the received data to stdout. You can have the default callback
+ write the data to a different file handle by passing a 'FILE *' to a file
+ opened for writing with the CURLOPT_FILE option.
+
+ Now, we need to take a step back and have a deep breath. Here's one of those
+ rare platform-dependent nitpicks. Did you spot it? On some platforms[2],
+ libcurl won't be able to operate on files opened by the program. Thus, if you
+ use the default callback and pass in a an open file with CURLOPT_FILE, it
+ will crash. You should therefore avoid this to make your program run fine
+ virtually everywhere.
+
+ There are of course many more options you can set, and we'll get back to a
+ few of them later. Let's instead continue to the actual transfer:
+
+    success = curl_easy_perform(easyhandle);
+
+ The curl_easy_perform() will connect to the remote site, do the necessary
+ commands and receive the transfer. Whenever it receives data, it calls the
+ callback function we previously set. The function may get one byte at a time,
+ or it may get many kilobytes at once. libcurl delivers as much as possible as
+ often as possible. Your callback function should return the number of bytes
+ it "took care of". If that is not the exact same amount of bytes that was
+ passed to it, libcurl will abort the operation and return with an error code.
+
+ When the transfer is complete, the function returns a return code that
+ informs you if it succeeded in its mission or not. If a return code isn't
+ enough for you, you can use the CURLOPT_ERRORBUFFER to point libcurl to a
+ buffer of yours where it'll store a human readable error message as well.
+
+ If you then want to transfer another file, the handle is ready to be used
+ again. Mind you, it is even preferred that you re-use an existing handle if
+ you intend to make another transfer. libcurl will then attempt to re-use the
+ previous
+
+
+When It Doesn't Work
+
+ There will always be times when the transfer fails for some reason. You might
+ have set the wrong libcurl option or misunderstood what the libcurl option
+ actually does, or the remote server might return non-standard replies that
+ confuse the library which then confuses your program.
+
+ There's one golden rule when these things occur: set the CURLOPT_VERBOSE
+ option to TRUE. It'll cause the library to spew out the entire protocol
+ details it sends, some internal info and some received protcol data as well
+ (especially when using FTP). If you're using HTTP, adding the headers in the
+ received output to study is also a clever way to get a better understanding
+ wht the server behaves the way it does. Include headers in the normal body
+ output with CURLOPT_HEADER set TRUE.
+
+ Of course there are bugs left. We need to get to know about them to be able
+ to fix them, so we're quite dependent on your bug reports! When you do report
+ suspected bugs in libcurl, please include as much details you possibly can: a
+ protocol dump that CURLOPT_VERBOSE produces, library version, as much as
+ possible of your code that uses libcurl, operating system name and version,
+ compiler name and version etc.
+
+ Getting some in-depth knowledge about the protocols involved is never wrong,
+ and if you're trying to do funny things, you might very well understand
+ libcurl and how to use it better if you study the appropriate RFC documents
+ at least briefly.
+
+
+Upload Data to a Remote Site
+
+ libcurl tries to keep a protocol independent approach to most transfers, thus
+ uploading to a remote FTP site is very similar to uploading data to a HTTP
+ server with a PUT request.
+
+ Of course, first you either create an easy handle or you re-use one existing
+ one. Then you set the URL to operate on just like before. This is the remote
+ URL, that we now will upload.
+
+ Since we write an application, we most likely want libcurl to get the upload
+ data by asking us for it. To make it do that, we set the read callback and
+ the custom pointer libcurl will pass to our read callback. The read callback
+ should have a prototype similar to:
+
+    size_t function(char *bufptr, size_t size, size_t nitems, void *userp);
+
+ Where bufptr is the pointer to a buffer we fill in with data to upload and
+ size*nitems is the size of the buffer and therefore also the maximum amount
+ of data we can return to libcurl in this call. The 'userp' pointer is the
+ custom pointer we set to point to a struct of ours to pass private data
+ between the application and the callback.
+
+    curl_easy_setopt(easyhandle, CURLOPT_READFUNCTION, read_function);
+
+    curl_easy_setopt(easyhandle, CURLOPT_INFILE, &filedata);
+
+ Tell libcurl that we want to upload:
+
+    curl_easy_setopt(easyhandle, CURLOPT_UPLOAD, TRUE);
+
+ A few protocols won't behave properly when uploads are done without any prior
+ knowledge of the expected file size. HTTP PUT is one example [1]. So, set the
+ upload file size using the CURLOPT_INFILESIZE like this:
+
+    curl_easy_setopt(easyhandle, CURLOPT_INFILESIZE, file_size);
+
+ When you call curl_easy_perform() this time, it'll perform all the necessary
+ operations and when it has invoked the upload it'll call your supplied
+ callback to get the data to upload. The program should return as much data as
+ possible in every invoke, as that is likely to make the upload perform as
+ fast as possible. The callback should return the number of bytes it wrote in
+ the buffer. Returning 0 will signal the end of the upload.
+
+
+Passwords
+
+ Many protocols use or even require that user name and password are provided
+ to be able to download or upload the data of your choice. libcurl offers
+ several ways to specify them.
+
+ Most protocols support that you specify the name and password in the URL
+ itself. libcurl will detect this and use them accordingly. This is written
+ like this:
+
+        protocol://user:password@example.com/path/
+
+ If you need any odd letters in your user name or password, you should enter
+ them URL encoded, as %XX where XX is a two-digit hexadecimal number.
+
+ libcurl also provides options to set various passwords. The user name and
+ password as shown embedded in the URL can instead get set with the
+ CURLOPT_USERPWD option. The argument passed to libcurl should be a char * to
+ a string in the format "user:password:". In a manner like this:
+
+        curl_easy_setopt(easyhandle, CURLOPT_USERPWD, "myname:thesecret");
+
+ Another case where name and password might be needed at times, is for those
+ users who need to athenticate themselves to a proxy they use. libcurl offers
+ another option for this, the CURLOPT_PROXYUSERPWD. It is used quite similar
+ to the CURLOPT_USERPWD option like this:
+
+        curl_easy_setopt(easyhandle, CURLOPT_PROXYUSERPWD, "myname:thesecret");
+ 
+ There's a long time unix "standard" way of storing ftp user names and
+ passwords, namely in the $HOME/.netrc file. The file should be made private
+ so that only the user may read it (see also the "Security Considerations"
+ chapter), as it might contain the password in plain text. libcurl has the
+ ability to use this file to figure out what set of user name and password to
+ use for a particular host. As an extension to the normal functionality,
+ libcurl also supports this file for non-FTP protocols such as HTTP. To make
+ curl use this file, use the CURLOPT_NETRC option:
+
+    curl_easy_setopt(easyhandle, CURLOPT_NETRC, TRUE);
+
+ And a very basic example of how such a .netrc file may look like:
+
+    machine myhost.mydomain.com
+    login userlogin
+    password secretword
+
+ All these examples have been cases where the password has been optional, or
+ at least you could leave it out and have libcurl attempt to do its job
+ without it. There are times when the password isn't optional, like when
+ you're using an SSL private key for secure transfers.
+
+ You can in this situation either pass a password to libcurl to use to unlock
+ the private key, or you can let libcurl prompt the user for it. If you prefer
+ to ask the user, then you can provide your own callback function that will be
+ called when libcurl wants the password. That way, you can control how the
+ question will appear to the user.
+
+ To pass the known private key password to libcurl:
+
+    curl_easy_setopt(easyhandle, CURLOPT_SSLKEYPASSWD, "keypassword");
+
+ To make a password callback:
+
+    int enter_passwd(void *ourp, const char *prompt, char *buffer, int len);
+    curl_easy_setopt(easyhandle, CURLOPT_PASSWDFUNCTION, enter_passwd);
+
+
+HTTP POSTing
+
+ We get many questions regarding how to issue HTTP POSTs with libcurl the
+ proper way. This chapter will thus include examples using both different
+ versions of HTTP POST that libcurl supports.
+
+ The first version is the simple POST, the most common version, that most HTML
+ pages using the <form> tag uses. We provide a pointer to the data and tell
+ libcurl to post it all to the remote site:
+
+    char *data="name=daniel&project=curl";
+    curl_easy_setopt(easyhandle, CURLOPT_POSTFIELDS, data);
+    curl_easy_setopt(easyhandle, CURLOPT_URL, "http://posthere.com/");
+
+    curl_easy_perform(easyhandle); /* post away! */
+
+ Simple enough, huh? Since you set the POST options with the
+ CURLOPT_POSTFIELDS, this automaticly switches the handle to use POST in the
+ upcoming request.
+
+ Ok, so what if you want to post binary data that also requires you to set the
+ Content-Type: header of the post? Well, binary posts prevents libcurl from
+ being able to do strlen() on the data to figure out the size, so therefore we
+ must tell libcurl the size of the post data. Setting headers in libcurl
+ requests are done in a generic way, by building a list of our own headers and
+ then passing that list to libcurl.
+
+    struct curl_slist *headers=NULL;
+    headers = curl_slist_append(headers, "Content-Type: text/xml");
+
+    /* post binary data */
+    curl_easy_setopt(easyhandle, CURLOPT_POSTFIELD, binaryptr);
+
+    /* set the size of the postfields data */
+    curl_easy_setopt(easyhandle, CURLOPT_POSTFIELDSIZE, 23);
+
+    /* pass our list of custom made headers */
+    curl_easy_setopt(easyhandle, CURLOPT_HTTPHEADER, headers);
+
+    curl_easy_perform(easyhandle); /* post away! */
+
+    curl_slist_free_all(headers); /* free the header list */
+
+ While the simple examples above cover the majority of all cases where HTTP
+ POST operations are required, they don't do multipart formposts. Multipart
+ formposts were introduced as a better way to post (possibly large) binary
+ data and was first documented in the RFC1867. They're called multipart
+ because they're built by a chain of parts, each being a single unit. Each
+ part has its own name and contents. You can in fact create and post a
+ multipart formpost with the regular libcurl POST support described above, but
+ that would require that you build a formpost yourself and provide to
+ libcurl. To make that easier, libcurl provides curl_formadd(). Using this
+ function, you add parts to the form. When you're done adding parts, you post
+ the whole form.
+
+ The following example sets two simple text parts with plain textual contents,
+ and then a file with binary contents and upload the whole thing.
+
+    struct HttpPost *post=NULL;
+    struct HttpPost *last=NULL;
+    curl_formadd(&post, &last,
+                 CURLFORM_COPYNAME, "name",
+                 CURLFORM_COPYCONTENTS, "daniel", CURLFORM_END);
+    curl_formadd(&post, &last,
+                 CURLFORM_COPYNAME, "project",
+                 CURLFORM_COPYCONTENTS, "curl", CURLFORM_END);
+    curl_formadd(&post, &last,
+                 CURLFORM_COPYNAME, "logotype-image",
+                 CURLFORM_FILECONTENT, "curl.png", CURLFORM_END);
+
+    /* Set the form info */
+    curl_easy_setopt(easyhandle, CURLOPT_HTTPPOST, post);
+
+    curl_easy_perform(easyhandle); /* post away! */
+
+    /* free the post data again */
+    curl_formfree(post);
+
+ Multipart formposts are chains of parts using MIME-style separators and
+ headers. It means that each one of these separate parts get a few headers set
+ that describe the individual content-type, size etc. To enable your
+ application to handicraft this formpost even more, libcurl allows you to
+ supply your own set of custom headers to such an individual form part. You
+ can of course supply headers to as many parts you like, but this little
+ example will show how you set headers to one specific part when you add that
+ to the post handle:
+
+    struct curl_slist *headers=NULL;
+    headers = curl_slist_append(headers, "Content-Type: text/xml");
+
+    curl_formadd(&post, &last,
+                 CURLFORM_COPYNAME, "logotype-image",
+                 CURLFORM_FILECONTENT, "curl.xml",
+                 CURLFORM_CONTENTHEADER, headers,
+                 CURLFORM_END);
+
+    curl_easy_perform(easyhandle); /* post away! */
+
+    curl_formfree(post); /* free post */
+    curl_slist_free_all(post); /* free custom header list */
+
+ Since all options on an easyhandle are "sticky", they remain the same until
+ changed even if you do call curl_easy_perform(), you may need to tell curl to
+ go back to a plain GET request if you intend to do such a one as your next
+ request. You force an easyhandle to back to GET by using the CURLOPT_HTTPGET
+ option:
+
+    curl_easy_setopt(easyhandle, CURLOPT_HTTPGET, TRUE);
+
+ Just setting CURLOPT_POSTFIELDS to "" or NULL will *not* stop libcurl from
+ doing a POST. It will just make it POST without any data to send!
+
+
+Showing Progress
+
+ For historical and traditional reasons, libcurl has a built-in progress meter
+ that can be switched on and then makes it presents a progress meter in your
+ terminal.
+
+ Switch on the progress meter by, oddly enough, set CURLOPT_NOPROGRESS to
+ FALSE. This option is set to TRUE by default.
+
+ For most applications however, the built-in progress meter is useless and
+ what instead is interesting is the ability to specify a progress
+ callback. The function pointer you pass to libcurl will then be called on
+ irregular intervals with information about the current transfer.
+
+ Set the progress callback by using CURLOPT_PROGRESSFUNCTION. And pass a
+ pointer to a function that matches this prototype:
+
+        int progress_callback(void *clientp,
+                              double dltotal,
+                              double dlnow,
+                              double ultotal,
+                              double ulnow);
+
+ If any of the input arguments is unknown, a 0 will be passed. The first
+ argument, the 'clientp' is the pointer you pass to libcurl with
+ CURLOPT_PROGRESSDATA. libcurl won't touch it.
+
+
+libcurl with C++
+
+ There's basicly only one thing to keep in mind when using C++ instead of C
+ when interfacing libcurl:
+
+    "The Callbacks Must Be Plain C"
+
+ So if you want a write callback set in libcurl, you should put it within
+ 'extern'. Similar to this:
+
+     extern "C" {
+       size_t write_data(void *ptr, size_t size, size_t nmemb,
+                         void *ourpointer)
+       {
+         /* do what you want with the data */
+       }
+    }
+
+ This will of course effectively turn the callback code into C. There won't be
+ any "this" pointer available etc.
+
+
+Proxies
+
+ What "proxy" means according to Merriam-Webster: "a person authorized to act
+ for another" but also "the agency, function, or office of a deputy who acts
+ as a substitute for another".
+
+ Proxies are exceedingly common these days. Companies often only offer
+ internet access to employees through their HTTP proxies. Network clients or
+ user-agents ask the proxy for docuements, the proxy does the actual request
+ and then it returns them.
+
+ libcurl has full support for HTTP proxies, so when a given URL is wanted,
+ libcurl will ask the proxy for it instead of trying to connect to the actual
+ host identified in the URL.
+
+ The fact that the proxy is a HTTP proxy puts certain restrictions on what can
+ actually happen. A requested URL that might not be a HTTP URL will be still
+ be passed to the HTTP proxy to deliver back to libcurl. This happens
+ transparantly, and an application may not need to know. I say "may", because
+ at times it is very important to understand that all operations over a HTTP
+ proxy is using the HTTP protocol. For example, you can't invoke your own
+ custom FTP commands or even proper FTP directory listings.
+
+  Proxy Options
+
+    To tell libcurl to use a proxy at a given port number:
+
+       curl_easy_setopt(easyhandle, CURLOPT_PROXY, "proxy-host.com:8080");
+
+    Some proxies require user authentication before allowing a request, and
+    you pass that information similar to this:
+
+       curl_easy_setopt(easyhandle, CURLOPT_PROXYUSERPWD, "user:password");
+
+    If you want to, you can specify the host name only in the CURLOPT_PROXY
+    option, and set the port number separately with CURLOPT_PROXYPORT.
+
+  Environment Variables
+
+    libcurl automaticly checks and uses a set of environment variables to know
+    what proxies to use for certain protocols. The names of the variables are
+    following an ancient de facto standard and are built up as
+    "[protocol]_proxy" (note the lower casing). Which makes the variable
+    'http_proxy' checked for a name of a proxy to use when the input URL is
+    HTTP. Following the same rule, the variable named 'ftp_proxy' is checked
+    for FTP URLs. Again, the proxies are always HTTP proxies, the different
+    names of the variables simply allows different HTTP proxies to be used.
+
+    The proxy environment variable contents should be in the format
+    "[protocol://]machine[:port]". Where the protocol:// part is simply
+    ignored if present (so http://proxy and bluerk://proxy will do the same)
+    and the optional port number specifies on which port the proxy operates on
+    the host. If not specified, the internal default port number will be used
+    and that is most likely *not* the one you would like it to be.
+
+    There are two special environment variables. 'all_proxy' is what sets
+    proxy for any URL in case the protocol specific variable wasn't set, and
+    'no_proxy' defines a list of hosts that should not use a proxy even though
+    a variable may say so. If 'no_proxy' is a plain asterisk ("*") it matches
+    all hosts.
+
+  SSL and Proxies
+
+    SSL is for secure point-to-point connections. This involves strong
+    encryption and similar things, which effectivly makes it impossible for a
+    proxy to operate as a "man in between" which the proxy's task is, as
+    previously discussed. Instead, the only way to have SSL work over a HTTP
+    proxy is to ask the proxy to tunnel trough everything without being able
+    to check or fiddle with the traffic.
+
+    Opening an SSL connection over a HTTP proxy is therefor a matter of asking
+    the proxy for a straight connection to the target host on a specified
+    port. This is made with the HTTP request CONNECT. ("please mr proxy,
+    connect me to that remote host").
+
+    Because of the nature of this operation, where the proxy has no idea what
+    kind of data that is passed in and out through this tunnel, this breaks
+    some of the very few advantages that come from using a proxy, such as
+    caching.  Many organizations prevent this kind of tunneling to other
+    destination port numbers than 443 (which is the default HTTPS port
+    number).
+
+  Tunneling Through Proxy
+
+    As explained above, tunneling is required for SSL to work and often even
+    restricted to the operation intended for SSL; HTTPS.
+
+    This is however not the only time proxy-tunneling might offer benefits to
+    you or your application.
+
+    As tunneling opens a direct connection from your application to the remote
+    machine, it suddenly also re-introduces the ability to do non-HTTP
+    operations over a HTTP proxy. You can in fact use things such as FTP
+    upload or FTP custom commands this way.
+
+    Again, this is often prevented by the adminstrators of proxies and is
+    rarely allowed.
+
+    Tell libcurl to use proxy tunneling like this:
+
+       curl_easy_setopt(easyhandle, CURLOPT_HTTPPROXYTUNNEL, TRUE);
+
+    In fact, there might even be times when you want to do plain HTTP
+    operations using a tunnel like this, as it then enables you to operate on
+    the remote server instead of asking the proxy to do so. libcurl will not
+    stand in the way for such innovative actions either!
+
+  Proxy Auto-Config
+
+    Netscape first came up with this. It is basicly a web page (usually using
+    a .pac extension) with a javascript that when executed by the browser with
+    the requested URL as input, returns information to the browser on how to
+    connect to the URL. The returned information might be "DIRECT" (which
+    means no proxy should be used), "PROXY host:port" (to tell the browser
+    where the proxy for this particular URL is) or "SOCKS host:port" (to
+    direct the brower to a SOCKS proxy).
+
+    libcurl has no means to interpret or evaluate javascript and thus it
+    doesn't support this. If you get yourself in a position where you face
+    this nasty invention, the following advice have been mentioned and used in
+    the past:
+
+    - Depending on the javascript complexity, write up a script that
+      translates it to another language and execute that.
+
+    - Read the javascript code and rewrite the same logic in another language.
+
+    - Implement a javascript interpreted, people have successfully used the
+      Mozilla javascript engine in the past.
+
+    - Ask your admins to stop this, for a static proxy setup or similar.
+
+
+Persistancy Is The Way to Happiness
+
+ Re-cycling the same easy handle several times when doing multiple requests is
+ the way to go.
+
+ After each single curl_easy_perform() operation, libcurl will keep the
+ connection alive and open. A subsequent request using the same easy handle to
+ the same host might just be able to use the already open connection! This
+ reduces network impact a lot.
+
+ Even if the connection is dropped, all connections involving SSL to the same
+ host again, will benefit from libcurl's session ID cache that drasticly
+ reduces re-connection time.
+
+ FTP connections that are kept alive saves a lot of time, as the command-
+ response roundtrips are skipped, and also you don't risk getting blocked
+ without permission to login again like on many FTP servers only allowing N
+ persons to be logged in at the same time.
+
+ libcurl caches DNS name resolving results, to make lookups of a previously
+ looked up name a lot faster.
+
+ Other interesting details that improve performance for subsequent requests
+ may also be added in the future.
+
+ Each easy handle will attempt to keep the last few connections alive for a
+ while in case they are to be used again. You can set the size of this "cache"
+ with the CURLOPT_MAXCONNECTS option. Default is 5. It is very seldom any
+ point in changing this value, and if you think of changing this it is often
+ just a matter of thinking again.
+
+ When the connection cache gets filled, libcurl must close an existing
+ connection in order to get room for the new one. To know which connection to
+ close, libcurl uses a "close policy" that you can affect with the
+ CURLOPT_CLOSEPOLICY option. There's only two polices implemented as of this
+ writing (libcurl 7.9.4) and they are:
+
+  CURLCLOSEPOLICY_LEAST_RECENTLY_USED simply close the one that hasn't been
+  used for the longest time. This is the default behavior.
+
+  CURLCLOSEPOLICY_OLDEST closes the oldest connection, the one that was
+  createst the longest time ago.
+
+ There are, or at least were, plans to support a close policy that would call
+ a user-specified callback to let the user be able to decide which connection
+ to dump when this is necessary and therefor is the CURLOPT_CLOSEFUNCTION an
+ existing option still today. Nothing ever uses this though and this will not
+ be used within the forseeable future either.
+
+ To force your upcoming request to not use an already existing connection (it
+ will even close one first if there happens to be one alive to the same host
+ you're about to operate on), you can do that by setting CURLOPT_FRESH_CONNECT
+ to TRUE. In a similar spirit, you can also forbid the upcoming request to be
+ "lying" around and possibly get re-used after the request by setting
+ CURLOPT_FORBID_REUSE to TRUE.
+
+
+Customizing Operations
+
+ There is an ongoing development today where more and more protocols are built
+ upon HTTP for transport. This has obvious benefits as HTTP is a tested and
+ reliable protocol that is widely deployed and have excellent proxy-support.
+
+ When you use one of these protocols, and even when doing other kinds of
+ programming you may need to change the traditional HTTP (or FTP or...)
+ manners. You may need to change words, headers or various data.
+
+ libcurl is your friend here too.
+
+ If just changing the actual HTTP request keyword is what you want, like when
+ GET, HEAD or POST is not good enough for you, CURLOPT_CUSTOMREQUEST is there
+ for you. It is very simple to use:
+
+    curl_easy_setopt(easyhandle, CURLOPT_CUSTOMREQUEST, "MYOWNRUQUEST");
+
+ When using the custom request, you change the request keyword of the actual
+ request you are performing. Thus, by default you make GET request but you can
+ also make a POST operation (as described before) and then replace the POST
+ keyword if you want to. You're the boss.
+
+ HTTP-like protocols pass a series of headers to the server when doing the
+ request, and you're free to pass any amount of extra headers that you think
+ fit. Adding headers are this easy:
+
+    struct curl_slist *headers;
+
+    headers = curl_slist_append(headers, "Hey-server-hey: how are you?");
+    headers = curl_slist_append(headers, "X-silly-content: yes");
+
+    /* pass our list of custom made headers */
+    curl_easy_setopt(easyhandle, CURLOPT_HTTPHEADER, headers);
+
+    curl_easy_perform(easyhandle); /* transfer http */
+
+    curl_slist_free_all(headers); /* free the header list */
+
+ ... and if you think some of the internally generated headers, such as
+ User-Agent:, Accept: or Host: don't contain the data you want them to
+ contain, you can replace them by simply setting them too:
+
+    headers = curl_slist_append(headers, "User-Agent: 007");
+    headers = curl_slist_append(headers, "Host: munged.host.line");
+
+ If you replace an existing header with one with no contents, you will prevent
+ the header from being sent. Like if you want to completely prevent the
+ "Accept:" header to be sent, you can disable it with code similar to this:
+
+    headers = curl_slist_append(headers, "Accept:");
+
+ Both replacing and cancelling internal headers should be done with careful
+ consideration and you should be aware that you may violate the HTTP protocol
+ when doing so.
+
+ There's only one aspect left in the HTTP requests that we haven't yet
+ mentioned how to modify: the version field. All HTTP requests includes the
+ version number to tell the server which version we support. libcurl speak
+ HTTP 1.1 by default. Some very old servers don't like getting 1.1-requests
+ and when dealing with stubborn old things like that, you can tell libcurl to
+ use 1.0 instead by doing something like this:
+
+    curl_easy_setopt(easyhandle, CURLOPT_HTTP_VERSION, CURLHTTP_VERSION_1_0);
+
+ Not all protocols are HTTP-like, and thus the above may not help you when you
+ want to make for example your FTP transfers to behave differently.
+
+ Sending custom commands to a FTP server means that you need to send the
+ comands exactly as the FTP server expects them (RFC959 is a good guide here),
+ and you can only use commands that work on the control-connection alone. All
+ kinds of commands that requires data interchange and thus needs a
+ data-connection must be left to libcurl's own judgement. Also be aware that
+ libcurl will do its very best to change directory to the target directory
+ before doing any transfer, so if you change directory (with CWD or similar)
+ you might confuse libcurl and then it might not attempt to transfer the file
+ in the correct remote directory.
+
+ A little example that deletes a given file before an operation:
+
+    headers = curl_slist_append(headers, "DELE file-to-remove");
+
+    /* pass the list of custom commands to the handle */
+    curl_easy_setopt(easyhandle, CURLOPT_QUOTE, headers);
+
+    curl_easy_perform(easyhandle); /* transfer ftp data! */
+
+    curl_slist_free_all(headers); /* free the header list */
+
+ If you would instead want this operation (or chain of operations) to happen
+ _after_ the data transfer took place the option to curl_easy_setopt() would
+ instead be called CURLOPT_POSTQUOTE and used the exact same way.
+
+ The custom FTP command will be issued to the server in the same order they
+ are added to the list, and if a command gets an error code returned back from
+ the server, no more commands will be issued and libcurl will bail out with an
+ error code (CURLE_FTP_QUOTE_ERROR). Note that if you use CURLOPT_QUOTE to
+ send commands before a transfer, no transfer will actually take place when a
+ quote command has failed.
+
+ If you set the CURLOPT_HEADER to true, you will tell libcurl to get
+ information about the target file and output "headers" about it. The headers
+ will be in "HTTP-style", looking like they do in HTTP.
+
+ The option to enable headers or to run custom FTP commands may be useful to
+ combine with CURLOPT_NOBODY. If this option is set, no actual file content
+ transfer will be performed.
+
+
+Cookies Without Chocolate Chips
+
+ In the HTTP sense, a cookie is a name with an associated value. A server
+ sends the name and value to the client, and expects it to get sent back on
+ every subsequent request to the server that matches the particular conditions
+ set. The conditions include that the domain name and path match and that the
+ cookie hasn't become too old.
+
+ In real-world cases, servers send new cookies to replace existing one to
+ update them. Server use cookies to "track" users and to keep "sessions".
+
+ Cookies are sent from server to clients with the header Set-Cookie: and
+ they're sent from clients to servers with the Cookie: header.
+
+ To just send whatever cookie you want to a server, you can use CURLOPT_COOKIE
+ to set a cookie string like this:
+
+    curl_easy_setopt(easyhandle, CURLOPT_COOKIE, "name1=var1; name2=var2;");
+
+ In many cases, that is not enough. You might want to dynamicly save whatever
+ cookies the remote server passes to you, and make sure those cookies are then
+ use accordingly on later requests.
+
+ One way to do this, is to save all headers you receive in a plain file and
+ when you make a request, you tell libcurl to read the previous headers to
+ figure out which cookies to use. Set header file to read cookies from with
+ CURLOPT_COOKIEFILE.
+
+ The CURLOPT_COOKIEFILE option also automaticly enables the cookie parser in
+ libcurl. Until the cookie parser is enabled, libcurl will not parse or
+ understand incoming cookies and they will just be ignored. However, when the
+ parser is enabled the cookies will be understood and the cookies will be kept
+ in memory and used properly in subsequent requests when the same handle is
+ used. Many times this is enough, and you may not have to save the cookies to
+ disk at all. Note that the file you specify to CURLOPT_COOKIEFILE doesn't
+ have to exist to enable the parser, so a common way to just enable the parser
+ and not read able might be to use a file name you know doesn't exist.
+
+ If you rather use existing cookies that you've previously received with your
+ Netscape or Mozilla browsers, you can make libcurl use that cookie file as
+ input. The CURLOPT_COOKIEFILE is used for that too, as libcurl will
+ automaticly find out what kind of file it is and act accordingly.
+
+ The perhaps most advanced cookie operation libcurl offers, is saving the
+ entire internal cookie state back into a Netscape/Mozilla formatted cookie
+ file. We call that the cookie-jar. When you set a file name with
+ CURLOPT_COOKIEJAR, that file name will be created and all received cookies
+ will be stored in it when curl_easy_cleanup() is called. This enabled cookies
+ to get passed on properly between multiple handles without any information
+ getting lost.

- *************************************************************************
- *
- *
- * 1998/01/10  (v2.8)
- *   Daniel
- *   - Updated version number.
- *   - Corrected a static non-zero prefixed width problem.
- *
- * 1998/11/17 - Daniel
- *   Added daprintf() and dvaprintf() for allocated printf() and vprintf().
- *   They return an allocated buffer with the result inside. The result must
- *   be free()ed!
- *
- * 1998/08/23 - breese
- *
- *   Converted all non-printable (and non-whitespace) characters into
- *   their decimal ASCII value preceeded by a '\' character
- *   (this only applies to snprintf family so far)
- *
- *   Added %S (which is the same as %#s)
- *
- * 1998/05/05 (v2.7)
- *
- *   Fixed precision and width qualifiers (%.*s)
- *
- *   Added support for snprintf()
- *
- *   Quoting (%#s) is disabled for the (nil) pointer
- *
- * 1997/06/09 (v2.6)
- *
- *   %#s means that the string will be quoted with "
- *   (I was getting tired of writing \"%s\" all the time)
- *
- *   [ERR] for strings changed to (nil)
- *
- * v2.5
- * - Added C++ support
- * - Prepended all internal functions with dprintf_
- * - Defined the booleans
- *
- * v2.4
- * - Added dvsprintf(), dvfprintf() and dvprintf().
- * - Made the formatting function available with the name _formatf() to enable
- *   other *printf()-inspired functions. (I considered adding a dmsprintf()
- *   that works like sprintf() but allocates the destination string and
- *   possibly enlarges it itself, but things like that should be done with the
- *   new _formatf() instead.)
- *
- * v2.3
- * - Small modifications to make it compile nicely at both Daniel's and
- *   Bjorn's place.
- *
- * v2.2
- * - Made it work with text to the right of the last %!
- * - Introduced dprintf(), dsprintf() and dfprintf().
- * - Float/double support enabled. This system is currently using the ordinary
- *   sprintf() function. NOTE that positional parameters, widths and precisions
- *   will still work like it should since the d-system takes care of that and
- *   passes that information re-formatted to the old sprintf().
- *
- * v2.1
- * - Fixed space padding (i.e %d was extra padded previously)
- * - long long output is supported
- * - alternate output is done correct like in %#08x
