   Changelog for the c-ares project
 
+Version 1.3.0 (August 29, 2004)
+
+* August 21
+
+- Alfredo Tupone provided a fix for the Windows code in get_iphlpapi_dns_info()
+  when getting the DNS server etc.
+
+* June 19
+
+- Added some checks for the addrinfo structure.
+
+* June 2
+
+- William Ahern:
+
+  Make UDP sockets non-blocking. I've confirmed that at least on Linux 2.4 a
+  read event can come back from poll() on a valid SOCK_DGRAM socket but
+  recv(2) will still block. This patch doesn't ignore EAGAIN in
+  read_udp_packets(), though maybe it should. (This patch was edited by Daniel
+  Stenberg and a new configure test was added (imported from curl's configure)
+  to properly detect what non-blocking socket approach to use.)
+
+  I'm not quite sure how this was happening, but I've been seeing PTR queries
+  which seem to return empty responses. At least, they were empty when calling
+  ares_expand_name() on the record. Here's a patch which guarantees to
+  NUL-terminate the expanded name. The old behavior failed to NUL-terminate if
+  len was 0, and this was causing strlen() to run past the end of the buffer
+  after calling ares_expand_name() and getting ARES_SUCCESS as the return
+  value. If q is not greater than *s then it's equal and *s is always
+  allocated with at least one byte.
+
+* May 16
+
+- Added ares_getnameinfo which mimics the getnameinfo API (another feature
+  that could use testing).
+
+* May 14
+
+- Added an inet_ntop function from BIND for systems that do not have it.
+
+* April 9
+
+- Made sortlist support IPv6 (this can probably use some testing).
+
+- Made sortlist support CIDR matching for IPv4.
+
+* April 8
+
+- Added preliminary IPv6 support to ares_gethostbyname. Currently, sortlist
+  does not work with IPv6. Also provided an implementation of bitncmp from
+  BIND for systems that do not supply this function. This will be used to add
+  IPv6 support to sortlist.
+
+- Made ares_gethostbyaddr support IPv6 by specifying AF_INET6 as the family.
+  The function can lookup IPv6 addresses both from files (/etc/hosts) and
+  DNS lookups.
+
+* April 7
+
+- Tupone Alfredo fixed includes of arpa/nameser_compat.h to build fine on Mac
+  OS X.
+
+* April 5
+
+- Dominick Meglio: Provided implementations of inet_net_pton and inet_pton
+  from BIND for systems that do not include these functions.
+
+* March 11, 2005
+
+- Dominick Meglio added ares_parse_aaaa_reply.c and did various
+  adjustments. The first little steps towards IPv6 support!
+
+* November 7
+
+- Fixed the VC project and makefile to use ares_cancel and ares_version
+
+* October 24
+
+- The released ares_version.h from 1.2.1 says 1.2.0 due to a maketgz flaw.
+  This is now fixed.
+
+Version 1.2.1 (October 20, 2004)
+
+* September 29
+
+- Henrik Stoerner fix: got a report that Tru64 Unix (the unix from Digital
+  when they made Alpha's) uses /etc/svc.conf for the purpose fixed below for
+  other OSes. He made c-ares check for and understand it if present.
+
+- Now c-ares will use local host name lookup _before_ DNS resolving by default
+  if nothing else is told.
+
+* September 26
+
+- Henrik Stoerner: found out that c-ares does not look at the /etc/host.conf
+  file to determine the sequence in which to search /etc/hosts and DNS.  So on
+  systems where this order is defined by /etc/host.conf instead of a "lookup"
+  entry in /etc/resolv.conf, c-ares will always default to looking in DNS
+  first, and /etc/hosts second.
+
+  c-ares now looks at
+
+  1) resolv.conf (for the "lookup" line);
+  2) nsswitch.fon (for the "hosts:" line);
+  3) host.conf (for the "order" line).
+
+  First match wins.
+
+- Dominick Meglio patched: C-ares on Windows assumed that the HOSTS file is
+  located in a static location. It assumed
+  C:\Windows\System32\Drivers\Etc. This is a poor assumption to make. In fact,
+  the location of the HOSTS file can be changed via a registry setting.
+
+  There is a key called DatabasePath which specifies the path to the HOSTS
+  file:
+  http://www.microsoft.com/technet/itsolutions/network/deploy/depovg/tcpip2k.mspx
+
+  The patch will make c-ares correctly consult the registry for the location
+  of this file.
+
+* August 29
+
+- Gisle Vanem fixed the MSVC build files.
+
+* August 20
+
+- Gisle Vanem made c-ares build and work with his Watt-32 TCP/IP stack.
+
+* August 13
+
+- Harshal Pradhan made a minor syntax change in ares_init.c to make it build
+  fine with MSVC 7.1
+
 * July 24
 
 - Made the lib get built static only if --enable-debug is used.

+.SH NAME
+ares_getnameinfo \- Address-to-nodename translation in protocol-independent manner
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B typedef void (*ares_nameinfo_callback)(void *\fIarg\fP, int \fIstatus\fP,
+.B	char *\fInode\fP, char *\fIservice\fP)
+.PP
+.B void ares_getnameinfo(ares_channel \fIchannel\fP, const struct sockaddr *\fIsa\fP,
+.B 	socklen_t \fIsalen\fP, int \fIflags\fP, ares_nameinfo_callback \fIcallback\fP,
+.B 	void *\fIarg\fP)
+.fi
+.SH DESCRIPTION
+The
+.B ares_getnameinfo
+function is defined for protocol-independent address translation. The function
+is a combination of \fIares_gethostbyaddr(3)\fP and \fIgetservbyport(3)\fP. The function will
+translate the address either by executing a host query on the name service channel
+identified by
+.IR channel 
+or it will attempt to resolve it locally if possible.
+The parameters
+.I sa
+and
+.I len
+give the address as a sockaddr structure, and
+.I flags
+gives the options that the function will use.  Valid flags are listed below:
+.TP 19
+.B ARES_NI_NOFQDN
+Only the nodename portion of the FQDN is returned for local hosts.
+.TP 19
+.B ARES_NI_NUMERICHOST
+The numeric form of the hostname is returned rather than the name.
+.TP 19
+.B ARES_NI_NAMEREQD
+An error is returned if the hostname cannot be found in the DNS.
+.TP 19
+.B ARES_NI_NUMERICSERV
+The numeric form of the service is returned rather than the name.
+.TP 19
+.B ARES_NI_TCP
+The service name is to be looked up for the TCP protocol.
+.TP 19
+.B ARES_NI_UDP
+The service name is to be looked up for the UDP protocol.
+.TP 19
+.B ARES_NI_SCTP
+The service name is to be looked up for the SCTP protocol.
+.TP 19
+.B ARES_NI_DCCP
+The service name is to be looked up for the DCCP protocol.
+.TP 19
+.B ARES_NI_NUMERICSCOPE
+The numeric form of the scope ID is returned rather than the name.
+.TP 19
+.B ARES_NI_LOOKUPHOST
+A hostname lookup is being requested.
+.TP 19
+.B ARES_NI_LOOKUPSERVICE
+A service name lookup is being requested.
+.PP
+When the query
+is complete or has 
+failed, the ares library will invoke \fIcallback\fP.  Completion or failure of 
+the query may happen immediately, or may happen during a later call to
+\fIares_process(3)\fP, \fIares_destroy(3)\fP or \fIares_cancel(3)\fP.
+.PP
+The callback argument
+.I arg
+is copied from the
+.B ares_getnameinfo
+argument
+.IR arg .
+The callback argument
+.I status
+indicates whether the query succeeded and, if not, how it failed.  It
+may have any of the following values:
+.TP 19
+.B ARES_SUCCESS
+The host lookup completed successfully.
+.TP 19
+.B ARES_ENOTIMP
+The ares library does not know how to look up addresses of type
+.IR family .
+.TP 19
+.B ARES_ENOTFOUND
+The address
+.I addr
+was not found.
+.TP 19
+.B ARES_ENOMEM
+Memory was exhausted.
+.TP 19
+.B ARES_EDESTRUCTION
+The name service channel
+.I channel
+is being destroyed; the query will not be completed.
+.TP 19
+.B ARES_EBADFLAGS
+The
+.I flags
+parameter contains an illegal value.
+.PP
+On successful completion of the query, the callback argument
+.I node
+contains a string representing the hostname (assuming 
+.B ARES_NI_LOOKUPHOST
+was specified). Additionally, 
+.I service
+contains a string representing the service name (assuming
+.B ARES_NI_LOOKUPSERVICE
+was specified).
+If the query did not complete successfully, or one of the values
+was not requested, 
+.I node
+or
+.I service
+will be 
+.BR NULL .

+.SH NAME
+ares_parse_aaaa_reply \- Parse a reply to a DNS query of type AAAA into a hostent
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_parse_aaaa_reply(const unsigned char *\fIabuf\fP, int \fIalen\fP,
+.B 	struct hostent **\fIhost\fP);
+.fi
+.SH DESCRIPTION
+The
+.B ares_parse_aaaa_reply
+function parses the response to a query of type AAAA into a
+.BR "struct hostent" .
+The parameters
+.I abuf
+and
+.I alen
+give the contents of the response.  The result is stored in allocated
+memory and a pointer to it stored into the variable pointed to by
+.IR host .
+It is the caller's responsibility to free the resulting host structure
+using
+.BR ares_free_hostent (3)
+when it is no longer needed.
+.SH RETURN VALUES
+.B ares_parse_aaaa_reply
+can return any of the following values:
+.TP 15
+.B ARES_SUCCESS
+The response was successfully parsed.
+.TP 15
+.B ARES_EBADRESP
+The response was malformatted.
+.TP 15
+.B ARES_ENODATA
+The response did not contain an answer to the query.
+.TP 15
+.B ARES_ENOMEM
+Memory was exhausted.
+.SH SEE ALSO
+.BR ares_gethostbyname (3),
+.BR ares_free_hostent (3)

+
+Condition
+
+ This document is written to describe the sitution as it is right now. libcurl
+ 7.14.0 is currently the latest version available. Things may (or perhaps
+ will) of course change in the future.
+
+ This document reflects my view and understanding of these things. Please tell
+ me where and how you think I'm wrong, and I'll try to correct my mistakes.
+
+Background 
+
+ The Free Software Foundation has deemed the Original BSD license[1] to be
+ "incompatible"[2] with GPL[3]. I'd rather say it is the other way around, but
+ the point is the same: if you distribute a binary version of a GPL program,
+ it MUST NOT be linked with any Original BSD-licenced parts or
+ libraries. Doing so will violate the GPL license. For a long time, very many
+ GPL licensed programs have avoided this license mess by adding an
+ exception[8] to their license. And many others have just closed their eyes
+ for this problem.
+
+ libcurl is MIT-style[4] licensed - how on earth did this dilemma fall onto
+ our plates?
+
+ libcurl is only a little library. libcurl can be built to use OpenSSL for its
+ SSL/TLS capabilities. OpenSSL is basically Original BSD licensed[5].
+
+ If libcurl built to use OpenSSL is used by a GPL-licensed application and you
+ decide to distribute a binary version of it (Linux distros - for example -
+ tend to), you have a clash. GPL vs Original BSD.
+
+ This dilemma is not libcurl-specific nor is it specific to any particular
+ Linux distro.
+
+Part of the Operating System
+
+ This would not be a problem if the used lib would be considered part of the
+ uderlying operating system, as then the GPL license has an exception
+ clause[6] that allows applications to use such libs without having to be
+ allowed to distribute it or its sources. Possibly some distros will claim
+ that OpenSSL is part of their operating system.
+
+ Debian does however not take this stance and has officially(?) claimed that
+ OpenSSL is not a required part of the Debian operating system
+
+Debian-legal
+
+ In August 2004 I figured I should start pulling people's attention to this to
+ see if anyone has any bright ideas or if they would dismiss my worries based
+ on some elegant writing I had missed somewhere:
+
+ My post to debian-legal on August 12 2004:
+
+        http://lists.debian.org/debian-legal/2004/08/msg00279.html
+
+ Several people agreed then that this is a known and rather big problem, but
+ the following discussion didn't result in much.
+
+GnuTLS
+
+ With the release of libcurl 7.14.0 (May 2005), it can now get built to use
+ GnuTLS instead of OpenSSL. GnuTLS is a LGPL[7] licensed library that offers a
+ matching set of features as OpenSSL does. Now, you can build and distribute
+ an SSL capable libcurl without including any Original BSD licensed code.
+
+ I believe Debian is the first distro to provide libcurl/GnutTLS packages.
+
+GnuTLS vs OpenSSL
+
+ While these two libraries offer similar features, they are not equal. Both
+ libraries have features the other one lacks. libcurl does not (yet) offer a
+ standardized stable ABI if you decide to switch from using libcurl-openssl to
+ libcurl-gnutls or vice versa. The GnuTLS support is very recent in libcurl
+ and it has not been tested nor used very extensively, while the OpenSSL
+ equivalent code has been used and thus matured for more than seven (7) years.
+
+ In August 2005, the debian-devel mailing list discovered the license issue as
+ a GPL licensed application wanted SSL capabilities from libcurl and thus was
+ forced to use the GnuTLS powered libcurl. For a reason that is unknown to me,
+ the application authors didn't want to or was unable to add an exception to
+ their GPL license. Alas, the license problem hit the fan again.
+
+The Better License, Original BSD or LGPL?
+
+ It isn't obvious or without debate to any objective interested party that
+ either of these licenses are the "better" or even the "preferred" one in a
+ generic situation.
+
+ Instead, I think we should accept the fact that the SSL/TLS libraries and
+ their different licenses will fit different applications and their authors
+ differently depending on the applications' licenses and their general usage
+ pattern (considering how LGPL libraries can be burdonsome for embedded
+ systems usage).
+
+More SSL Libraries
+
+ In libcurl, there's no stopping us here. There are at least a few more Open
+ Source/Free SSL/TLS libraries and we would very much like to support them as
+ well, to offer application authors an even wider scope of choice.
+
+Application Angle of this Problem
+
+ libcurl is built to use one SSL/TLS library. It uses a single fixed name (by
+ default), and applications are built/linked to use that single lib. Replacing
+ one libcurl instance with another one that uses the other SSL/TLS library
+ might break one or more applications (due to ABI differences and/or different
+ feature set). You want your application to use the libcurl it was built for.
+
+Project cURL Angle of this Problem
+
+ We distribute libcurl and everyone may build libcurl with either library. At
+ their choice. This problem is not directly a problem of ours. It merely
+ affects users - GPL application authors only - of our lib as it comes
+ included and delivered on some distros.
+
+Distro Angle of this Problem
+
+ A distro can provide separate libcurls built with different SSL/TLS libraries
+ to work around this, but at least Debian seems to be very hostile against
+ such an approach, probably since it makes things like devel packages for the
+ different libs collide since they would provide the same include files and
+ man pages etc.
+
+Fixing the Only Problem
+
+ The only problem is thus for distributions that want to offer libcurl
+ versions built with more than one SSL/TLS library.
+
+ Since multiple libcurl binaries using different names are ruled out, we need
+ to come up with a way to have one single libcurl that someone uses different
+ underlying libraries. The best(?) approach currently suggested involves this:
+
+ A new intermediate library (named lib2 so far in the discussions) with the
+ single purpose of providing libcurl with SSL/TLS capabilities. It would have
+ a unified API and ABI no matter what underlying library it would use.
+
+ There would be one lib2 binary provided for each supported SSL/TLS library.
+ For example: lib2-openssl, lib2-gnutls, lib2-yassl, lib2-matrixssl and
+ lib2-nossl. Yes, take note of the last one that provides the lib2 ABI but
+ that lacks the actual powers.
+
+ When libcurl is built and linked, it will be linked against a lib2 with the
+ set ABI.
+
+ When you link an app against libcurl, it would also need to provide one of
+ the (many) lib2 libs to decide what approach that fits the app. An app that
+ doesn't want SSL at all would still need to link with the lib2-nossl lib.
+
+ GPL apps can pick the lib2-gnutls, others may pick the lib2-openssl.
+
+ This concept works equally well both for shared and static libraries.
+
+ A positive side effect of this approach could be a more generic "de facto"
+ standard API for SSL/TLS libraries.
+
+When Will This Happen
+
+ Note again that this is not a problem in curl, it doesn't solve any actual
+ technical problems in our project. Don't hold your breath for this to happen
+ very soon (if at all) unless you step forward and contribute.
+
+ The suggestion that is outlined above is still only a suggestion. Feel free
+ to bring a better idea!
+
+ Also, to keep in mind: I don't want this new concept to have too much of an
+ impact on the existing code. Preferably it should be possible to build the
+ code like today (without the use of lib2), should you decide to ignore the
+ problems outlined in this document.

+  3.16 What certificates do I need when I use SSL?
+
+  There are three different kinds of "certificates" to keep track of when we
+  talk about using SSL-based protocols (HTTPS or FTPS) using curl or libcurl.
+
+  - Client certificate. The server you communicate may require that you can
+    provide this in order to prove that you actually are who you claim to be.
+    If the server doesn't require this, you don't need a client certificate.
+
+  - Server certificate. The server you communicate with has a server
+    certificate. You can and should verify this certificate to make sure that
+    you are truly talking to the real server and not a server impersonating
+    it. The server certificate verification process is made by using a
+    Certificate Authority certificate ("CA cert") that was used to sign the
+    server certificate. Server certificate verification is enabled by default
+    in curl and libcurl and is often the reason for problems as explained in
+    FAQ entry 4.12 and the SSLCERTS document
+    (http://curl.haxx.se/docs/sslcerts.html). Server certificates that are
+    "self-signed" or otherwise signed by a CA that you do not have a CA cert
+    for, cannot be verified. If the verification during a connect fails, you
+    are refused access. You then need to explicitly disable the verification
+    to connect to the server.
+
+  - Certificate Authority certificate ("CA cert"). You often have several CA
+    certs in a CA cert bundle that can be used to verify a server certificate
+    that was signed by one of the authorities in the bundle. curl comes with a
+    default CA cert bundle. You can override the default.
+
+  3.17 How do I list the root dir of an FTP server?
+
+  There are two ways. The way defined in the RFC is to use an encoded slash
+  in the first path part. List the "/tmp" dir like this:
+
+     curl ftp://ftp.sunet.se/%2ftmp/
+
+  or the not-quite-kosher-but-more-readable way, by simply starting the path
+  section of the URL with a slash:
+
+     curl ftp://ftp.sunet.se//tmp/

+  4.14 Redirects work in browser but not with curl!
+
+  curl supports HTTP redirects fine (see item 3.8). Browsers generally support

+
+    1 - Meta tags. You can write a HTML tag that will cause the browser to

+
+    2 - Javascript. You can write a javascript program embeded in a HTML page
+        that redirects the browser to another given URL.
+
+  There is no way to make curl follow these redirects. You must either

+
+  libcurl includes a number of different name resolve functions:
+
+  - The non-ipv6 resolver that can use one out of four host name resolve calls
+    (depending on what your system supports):
+
+    A - gethostbyname()
+    B - gethostbyname_r() with 3 arguments
+    C - gethostbyname_r() with 5 arguments
+    D - gethostbyname_r() with 6 arguments
+
+  - The ipv6-resolver that uses getaddrinfo()
+
+  - The c-ares based name resolver that uses the c-ares library for resolves.
+
+  - The Windows threaded resolver. It use:
+
+    A - gethostbyname() on plain ipv4 windows hosts
+    B - getaddrinfo() on ipv6-enabled windows hosts
+
+  Also note that libcurl never resolves or reverse-lookups addresses given as
+  pure numbers, such as 127.0.0.1 or ::1.
+
+  5.10 How do I prevent libcurl from writing the response to stdout?
+
+  libcurl provides a default built-in write function that writes received data
+  to stdout. Set a WRITEFUNCTION to receive the data, or possibly set
+  WRITEDATA to a different FILE * handle.
+
+  5.11 How do I make libcurl not receive the whole HTTP response?
+
+  You make the write callback (or progress callback) return an error and
+  libcurl will then abort the transfer.
+
+  5.12 Can I make libcurl fake or hide my real IP address?
+
+  No. libcurl operates on a higher level than so. Besides, faking IP address
+  would imply sending IP packages with a made-up source address, and then you
+  normally get a problem with intercepting the packages sent back as they
+  would then not be routed to you!
+
+  If you use a proxy to access remote sites, the sites will not see your local
+  IP address but instead the address of the proxy.
+
+  Also note that on many networks NATs or other IP-munging techniques are used
+  that makes you see and use a different IP address locally than what the
+  remote server will see you coming from.

+
+  7.1 What is PHP/CURL?
+
+  The module for PHP that makes it possible for PHP programs to access curl-
+  functions from within PHP.
+
+  In the cURL project we call this module PHP/CURL to differentiate it from
+  curl the command line tool and libcurl the library. The PHP team however
+  does not refer to it like this (for unknown reasons). They call it plain
+  CURL (often using all caps) which causes much confusion to users which in
+  turn gives us a higher question load.
+
+  7.2 Who write PHP/CURL?
+
+  PHP/CURL is a module that comes with the regular PHP package. It depends and
+  uses libcurl, so you need to have libcurl installed properly first before
+  PHP/CURL can be used. PHP/CURL is written by Sterling Hughes.
+
+  7.3 Can I perform multiple requests using the same handle?
+
+  Yes - at least in PHP version 4.3.8 and later (this has been known to not
+  work in earlier versions, but the exact version when it started to work is
+  unknown to me).
+
+  After a transfer, you just set new options in the handle and make another
+  transfer. This will make libcurl to re-use the same connection if it can.

+CROSS COMPILE
+=============
+
+   (This section was graciously brought to us by Jim Duey, with additions by
+   Dan Fandrich)
+
+   Download and unpack the cURL package.  Version should be 7.9.1 or later.
+
+   'cd' to the new directory. (e.g. cd curl-7.12.3)
+
+   Set environment variables to point to the cross-compile toolchain and call
+   configure with any options you need.  Be sure and specify the '--host' and
+   '--build' parameters at configuration time.  The following script is an
+   example of cross-compiling for the IBM 405GP PowerPC processor using the
+   toolchain from MonteVista for Hardhat Linux.
+
+   (begin script)
+
+   #! /bin/sh
+
+   export PATH=$PATH:/opt/hardhat/devkit/ppc/405/bin
+   export CPPFLAGS="-I/opt/hardhat/devkit/ppc/405/target/usr/include"
+   export AR=ppc_405-ar
+   export AS=ppc_405-as
+   export LD=ppc_405-ld
+   export RANLIB=ppc_405-ranlib
+   export CC=ppc_405-gcc
+   export NM=ppc_405-nm
+
+   ./configure --target=powerpc-hardhat-linux \
+	--host=powerpc-hardhat-linux \
+	--build=i586-pc-linux-gnu \
+	--prefix=/opt/hardhat/devkit/ppc/405/target/usr/local \
+	--exec-prefix=/usr/local
+
+   (end script)
+
+   You may also need to provide a parameter like '--with-random=/dev/urandom'
+   to configure as it cannot detect the presence of a random number
+   generating device for a target system.  The '--prefix' parameter
+   specifies where cURL will be installed.  If 'configure' completes
+   successfully, do 'make' and 'make install' as usual.
+
+   In some cases, you may be able to simplify the above commands to as
+   little as:
+
+       ./configure --host=ARCH-OS
+
+   There are a number of configure options that can be used to reduce the
+   size of libcurl for embedded applications where binary size is an
+   important factor.  First, be sure to set the CFLAGS environment variable
+   when configuring with any compiler optimization flags to reduce the
+   size of the binary.  For gcc, this would mean at minimum:
+
+      env CFLAGS='-Os' ./configure ...
+
+   Be sure to specify as many --disable- and --without- flags on the configure
+   command-line as you can to disable all the libcurl features that you
+   know your application is not going to need.  Besides specifying the
+   --disable-PROTOCOL flags for all the types of URLs your application
+   will not use, here are some other flags that can reduce the size of the
+   library:
+
+     --disable-ares (disables support for the ARES DNS library)
+     --disable-cookies (disables support for HTTP cookies)
+     --disable-crypto-auth (disables HTTP cryptographic authentication)
+     --disable-ipv6 (disables support for IPv6)
+     --disable-verbose (eliminates debugging strings and error code strings)
+     --without-libidn (disables support for the libidn DNS library)
+     --without-ssl (disables support for SSL/TLS)
+     --without-zlib (disables support for on-the-fly decompression)
+
+   You may find that statically linking libcurl to your application will
+   result in a lower total size.

@@ -3,50 +3,102 @@ join in and help us correct one or more of these! Also be sure to check the
 changelog of the current development status, as one or more of these problems
 may have been fixed since this was written!
 
-* To get HTTP Negotiate authentication to work fine, you need to provide a
+25. When doing a CONNECT request with curl it doesn't properly handle if the
+  proxy closes the connection within the authentication "negotiation phase".
+  Like if you do HTTPS or similar over a proxy and you use perhaps
+  --proxy-anyauth. There's work in progress on this problem, and a recent
+  patch was posted here: http://curl.haxx.se/mail/lib-2005-08/0074.html
+
+24. Harshal Pradhan's Use-after-free with libcurl+ares. This probably occurs
+  because there is a pending ares callback that gets called after the
+  connection struct has been freed in libcurl:
+        http://curl.haxx.se/mail/lib-2005-08/0022.html
+  Fixing this properly most likely requires a new c-ares function.
+
+23. We don't support SOCKS for IPv6. We don't support FTPS over a SOCKS proxy.
+  We don't have any test cases for SOCKS proxy. We probably have even more
+  bugs and lack of features when a SOCKS proxy is used.
+
+22. Sending files to a FTP server using curl on VMS, might lead to curl
+  complaining on "unaligned file size" on completion. The problem is related
+  to VMS file structures and the perceived file sizes stat() returns. A
+  possible fix would involve sending a "STRU VMS" command.
+  http://sourceforge.net/support/tracker.php?aid=1156287
+  
+21. FTP ASCII transfers do not follow RFC959. They don't convert the data
+   accordingly (not for sending nor for receiving). RFC 959 section 3.1.1.1
+   clearly describes how this should be done:
+
+     The sender converts the data from an internal character representation to
+     the standard 8-bit NVT-ASCII representation (see the Telnet
+     specification).  The receiver will convert the data from the standard
+     form to his own internal form.
+
+19. FTP 3rd party transfers with the multi interface doesn't work. Test:
+  define CURL_MULTIEASY, rebuild curl, run test case 230 - 232.
+
+18. test case 57 has </test> that should be </client> but when corrected, the
+  test case fails!
+
+16. FTP URLs passed to curl may contain NUL (0x00) in the RFC 1738 <user>,
+  <password>, and <fpath> components, encoded as "%00".  The problem is that
+  curl_unescape does not detect this, but instead returns a shortened C
+  string.  From a strict FTP protocol standpoint, NUL is a valid character
+  within RFC 959 <string>, so the way to handle this correctly in curl would
+  be to use a data structure other than a plain C string, one that can handle
+  embedded NUL characters.  From a practical standpoint, most FTP servers
+  would not meaningfully support NUL characters within RFC 959 <string>,
+  anyway (e.g., UNIX pathnames may not contain NUL).
+
+14. Test case 165 might fail on system which has libidn present, but with an
+  old iconv version (2.1.3 is a known bad version), since it doesn't recognize
+  the charset when named ISO8859-1. Changing the name to ISO-8859-1 makes the
+  test pass, but instead makes it fail on Solaris hosts that use its native
+  iconv.
+
+13. curl version 7.12.2 fails on AIX if compiled with --enable-ares.
+  The workaround is to combine --enable-ares with --disable-shared
+
+12. When connecting to a SOCKS proxy, the (connect) timeout is not properly
+  acknowledged after the actual TCP connect (during the SOCKS "negotiate"
+  phase). Pointed out by Lucas. Fix: need to select() and timeout properly.
+
+11. Using configure --disable-[protocol] may cause 'make test' to fail for
+  tests using the disabled protocol(s).
+
+10. To get HTTP Negotiate authentication to work fine, you need to provide a
   (fake) user name (this concerns both curl and the lib) because the code
   wrongly only considers authentication if there's a user name provided.

-
-* --limit-rate using -d or -F does not work. This is because the limit logic
   is provided by the curl app in its read/write callbacks, and when doing
   -d/-F the callbacks aren't used! Bug report #921395.

+8. Doing resumed upload over HTTP does not work with '-C -', because curl
   doesn't do a HEAD first to get the initial size. This needs to be done
   manually for HTTP PUT resume to work, and then '-C [index]'.
 
-* CURLOPT_USERPWD and CURLOPT_PROXYUSERPWD have no way of providing user names
+7. CURLOPT_USERPWD and CURLOPT_PROXYUSERPWD have no way of providing user names
   that contain a colon. This can't be fixed easily in a backwards compatible
   way without adding new options (and then, they should most probably allow
   setting user name and password separately).
 
-* libcurl ignores empty path parts in FTP URLs, whereas RFC1738 states that
+6. libcurl ignores empty path parts in FTP URLs, whereas RFC1738 states that
   such parts should be sent to the server as 'CWD ' (without an argument).
   The only exception to this rule, is that we knowingly break this if the
   empty part is first in the path, as then we use the double slashes to
   indicate that the user wants to reach the root dir (this exception SHALL
   remain even when this bug is fixed).

+
+ Doing fancy stuff, you may need to add or change elements of a single curl
+ request.
+
+ For example, you can change the POST request to a PROPFIND and send the data
+ as "Content-Type: text/xml" (instead of the default Content-Type) like this:
+
+        curl -d "<xml>" -H "Content-Type: text/xml" -X PROPFIND url.com

+ You can delete a default header by providing one without content. Like you
+ can ruin the request by chopping off the Host: header:
+
+        curl -H "Host:" http://mysite.com
+
+ You can add headers the same way. Your server may want a "Destination:"
+ header, and you can add it:
+
+        curl -H "Destination: http://moo.com/nowhere" http://url.com
+
+13. Debug
+
+ Many times when you run curl on a site, you'll notice that the site doesn't
+ seem to respond the same way to your curl requests as it does to your
+ browser's.
+
+ Then you need to start making your curl requests more similar to your
+ browser's requests:
+
+ * Use the --trace-ascii option to store fully detailed logs of the requests
+   for easier analyzing and better understanding
+
+ * Make sure you check for and use cookies when needed (both reading with -b
+   and writing with -c)
+
+ * Set user-agent to one like a recent popular browser does
+
+ * Set referer like it is set by the browser
+
+ * If you use POST, make sure you send all the fields and in the same order as
+   the browser does it. (See chapter 4.5 above)
+
+ A very good helper to make sure you do this right, is the LiveHTTPHeader tool
+ that lets you view all headers you send and receive with Mozilla/Firefox
+ (even when using HTTPS).
+
+ A more raw approach is to capture the HTTP traffic on the network with tools
+ such as ethereal or tcpdump and check what headers that were sent and
+ received by the browser. (HTTPS makes this technique inefficient.)

  protocol.
