325391aef9 Albert Chin:
Forgot one case. On HP-UX 11.00, gethostbyname_r() is properly defined
if -D_REENTRANT is used. Without it, the compiler still accepts the
function prototype but gives a warning about hostent_data going out of
scope. This is because struct hostent_data is not declared. So, we
force an error by trying to set a variable to the struct.

History of Changes
Version 7.9.4
- no changes since pre-release
Version 7.9.4-pre2
Daniel (3 February 2002)
- Eric Melville provided a few spelling corrections in the curl man page.
Daniel (1 February 2002)
- Andreas Damm corrected the unconditional use of gmtime() in getdate, it now
uses gmtime_r() on all hosts that have it.
Daniel (31 January 2002)
- An anonymous bug report identified a problem in the DNS caching which made it
sometimes allocate one byte too little to store the cache entry in. This
happened when the port number started with 1!
- Albert Chin provided a patch that improves the gethostbyname_r() configure
check on HP-UX 11.00.
Version 7.9.4-pre1
Daniel (30 January 2002)
- Georg Horn found another way the SSL reading failed due to the non-blocking
state of the sockets! I fixed.
Daniel (29 January 2002)
- Multipart formposts now send the full request properly, including the CRLF.
They were previously treated as part of the post data.
- The upload byte counter bugged.
- T. Bharath pointed out that we seed SSL on every connect, which is a time-
consuming operation that should only be needed to do once. We patched
libcurl to now only seed on the first connect when unseeded. The seeded
status is global so it'll now only happen once during a program's life time.
If the random_file or egdsocket is set, the seed will be re-made though.
- Giaslas Georgios introduced CURLINFO_CONTENT_TYPE that lets
curl_easy_getinfo() read the content-type from the previous request.
Daniel (28 January 2002)
- Kjetil Jacobsen found a way to crash curl and after much debugging, it
turned out it was a IPv4-linux only problem introduced in 7.9.3 related to
name resolving.
- Andreas Damm posted a huge patch that made the curl_getdate() function fully
reentrant!
- Steve Marx pointed out that you couldn't mix CURLOPT_CUSTOMREQUEST with
CURLOPT_POSTFIELDS. You can now!
Daniel (25 January 2002)
- Krishnendu Majumdar pointed out that the header length counter was not reset
between multiple requests on the same handle.
- Pedro Neves rightfully questioned why curl always append \r\n to the data
that is sent in HTTP POST requests. Unfortunately, this broke the test suite
as the test HTTP server is lame enough not to deal with this... :-O
- Following Location: headers when the connection didn't close didn't work as
libcurl didn't properly stop reading. This problem was added in 7.9.3 due to
the restructured internals. 'Frank' posted a bug report about this.
Daniel (24 January 2002)
- Kevin Roth very quickly spotted that we wrongly installed the example
programs that were built in the multi directory, when 'make install' was
used. :-/

proxy is using the HTTP protocol. For example, you can't invoke your own
custom FTP commands or even proper FTP directory listings.
To tell libcurl to use a proxy at a given port number:
Proxy Options
curl_easy_setopt(easyhandle, CURLOPT_PROXY, "proxy-host.com:8080");
To tell libcurl to use a proxy at a given port number:
Some proxies require user authentication before allowing a request, and you
pass that information similar to this:
curl_easy_setopt(easyhandle, CURLOPT_PROXY, "proxy-host.com:8080");
curl_easy_setopt(easyhandle, CURLOPT_PROXYUSERPWD, "user:password");
Some proxies require user authentication before allowing a request, and
you pass that information similar to this:
[ environment variables, SSL, tunneling, automatic proxy config (.pac) ]
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.
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 built in 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. Note that if you use CURLOPT_QUOTE to send commands before a
transfer, no transfer will actually take place then.

THIS DOES NOT WORK
***************************************************************************
Things in curl-land have changed, but the test suite has not been fixed
accordingly and thus, the test suite is currently more or less useless.
*PLEASE* help us fixing this. We have to make our new test server written
in C work and get used instead of the perl version previously used.
The working version of the test server is found here:
http://curl.haxx.se/dev/sws-0.2.tar.gz
If you unpack this in the tests/ directory and run the server in there, you
can actually get test-responses if you do like this:
\$ ./sws 8080 &
