TODO
For the future
Ok, this is what I wanna do with Curl. Please tell me what you think, and
please don't hesitate to contribute and send me patches that improve this
product! (Yes, you may add things not mentioned here, these are just a
few teasers...)
* Make sure the low-level interface works. highlevel.c should basically be
possible to write using that interface. Document the low-level interface
* Add asynchronous name resolving, as this enables full timeout support for
fork() systems.
* Move non-URL related functions that are used by both the lib and the curl
application to a separate "portability lib".
* Add support for other languages than C. C++ and perl comes to mind. Python?
* Improve the -K config file parser (the parameter following the flag should
be possible to get specified *exactly* as it is done on a shell command
line).
* rtsp:// support -- "Real Time Streaming Protocol" (RFC 2326)
* "Content-Encoding: compress/gzip/zlib"
HTTP 1.1 clearly defines how to get and decode compressed documents. There
is the zlib that is pretty good at decompressing stuff. This work was
started in October 1999 but halted again since it proved more work than we
thought. It is still a good idea to implement though.
* Authentication: NTLM. It would be cool to support that MS crap called NTLM
authentication. MS proxies and servers sometime require that. Since that
protocol is a proprietary one, it involves reverse engineering and network
sniffing. This should however be a library-based functionality. There are a
few different efforts "out there" to make open source HTTP clients support
this and it should be possible to take advantage of other people's hard
work.
* RFC2617 compliance, "Digest Access Authentication"
A valid test page seem to exist at:
http://hopf.math.nwu.edu/testpage/digest/
And some friendly person's server source code is available at
http://hopf.math.nwu.edu/digestauth/index.html
Then there's the Apache mod_digest source code too of course. It seems as
if Netscape doesn't support this, and not many servers do. Although this is
a lot better authentication method than the more common "Basic". Basic
sends the password in cleartext over the network, this "Digest" method uses
a challange-response protocol which increases security quite a lot.
* Multiple Proxies?
Is there anyone that actually uses serial-proxies? I mean, send CONNECT to
the first proxy to connect to the second proxy to which you send CONNECT to
connect to the remote host (or even more iterations). Is there anyone
wanting curl to support it? (Not that it would be hard, just confusing...)
* Other proxies
Ftp-kind proxy, Socks5, whatever kind of proxies are there?
* IPv6 Awareness and support
Where ever it would fit. configure search for v6-versions of a few
functions and then use them instead is of course the first thing to do...
RFC 2428 "FTP Extensions for IPv6 and NATs" will be interesting. PORT
should be replaced with EPRT for IPv6, and EPSV instead of PASV.
* SSL for more protocols, like SSL-FTP...
(http://search.ietf.org/internet-drafts/draft-murray-auth-ftp-ssl-05.txt)
* HTTP POST resume using Range:
* Make curl capable of verifying the server's certificate when connecting
with HTTPS://.
