- How cURL Became Like This
- In the second half of 1997, Daniel Stenberg came up with the idea to make
- currency-exchange calculations available to Internet Relay Chat (IRC)
- users. All the necessary data are published on the Web; he just needed to
- automate their retrieval.
- Daniel simply adopted an existing command-line open-source tool, httpget, that
- Brazilian Rafael Sagula had written. After a few minor adjustments, it did
- just what he needed.
- Soon, he found currencies on a GOPHER site, so support for that had to go in,
- and not before long FTP download support was added as well. The name of the
- project was changed to urlget to better fit what it actually did now, since
- the http-only days were already passed.
- The project slowly grew bigger. When upload capabilities were added and the
- name once again was misleading, a second name change was made and on March 20,
- 1998 curl 4 was released. (The version numbering from the previous names was
- kept.)
- (Unrelated to this project a company called Curl Corporation registered a US
- trademark on the name "CURL" on May 18 1998. That company had then already
- registered the curl.com domain back in November of the previous year. All this
- was revealed to us much later.)
- SSL support was added, powered by the SSLeay library.
- August 1998, first announcement of curl on freshmeat.net.
- October 1998, with the curl 4.9 release and the introduction of cookie
- support, curl was no longer released under the GPL license. Now we're at 4000
- lines of code, we switched over to the MPL license to restrict the effects of
- "copyleft".
- November 1998, configure script and reported successful compiles on several
- major operating systems. The never-quite-understood -F option was added and
- curl could now simulate quite a lot of a browser. TELNET support was added.
- Curl 5 was released in December 1998 and introduced the first ever curl man
- page. People started making Linux RPM packages out of it.
- January 1999, DICT support added.
- OpenSSL took over where SSLeay was abandoned.
- May 1999, first Debian package.
- August 1999, LDAP:// and FILE:// support added. The curl web site gets 1300
- visits weekly.
- Released curl 6.0 in September. 15000 lines of code.
- December 28 1999, added the project on Sourceforge and started using its
- services for managing the project.
- Spring 2000, major internal overhaul to provide a suitable library interface.
- The first non-beta release was named 7.1 and arrived in August. This offered
- the easy interface and turned out to be the beginning of actually getting
- other software and programs to get based on and powered by libcurl. Almost
- 20000 lines of code.
- August 2000, the curl web site gets 4000 visits weekly.
- The PHP guys adopted libcurl already the same month, when the first ever third
- party libcurl binding showed up. CURL has been a supported module in PHP since
- the release of PHP 4.0.2. This would soon get followers. More than 16
- different bindings exist at the time of this writing.
- September 2000, kerberos4 support was added.
- In November 2000 started the work on a test suite for curl. It was later
- re-written from scratch again. The libcurl major SONAME number was set to 1.
- January 2001, Daniel released curl 7.5.2 under a new license again: MIT (or
- MPL). The MIT license is extremely liberal and can be used combined with GPL
- in other projects. This would finally put an end to the "complaints" from
- people involved in GPLed projects that previously were prohibited from using
- libcurl while it was released under MPL only. (Due to the fact that MPL is
- deemed "GPL incompatible".)
- curl supports HTTP 1.1 starting with the release of 7.7, March 22 2001. This
- also introduced libcurl's ability to do persistent connections. 24000 lines of
- code. The libcurl major SONAME number was bumped to 2 due to this overhaul.
- The first experimental ftps:// support was added in March 2001.
- August 2001. curl is bundled in Mac OS X, 10.1. It was already becoming more
- and more of a standard utility of Linux distributions and a regular in the BSD
- ports collections. The curl web site gets 8000 visits weekly. Curl Corporation
- contacted Daniel to discuss "the name issue". After Daniel's reply, they have
- never since got in touch again.
- September 2001, libcurl 7.9 introduces cookie jar and curl_formadd(). During
- the forthcoming 7.9.x releases, we introduced the multi interface slowly and
- without much whistles.
- June 2002, the curl web site gets 13000 visits weekly. curl and libcurl is
- 35000 lines of code. Reported successful compiles on more than 40 combinations
- of CPUs and operating systems.
- To estimate number of users of the curl tool or libcurl library is next to
- impossible. Around 5000 downloaded packages each week from the main site gives
- a hint, but the packages are mirrored extensively, bundled with numerous OS
- distributions and otherwise retrieved as part of other software.
- September 2002, with the release of curl 7.10 it is released under the MIT
- license only.
- January 2003. Started working on the distributed curl tests. The autobuilds.
- February 2003, the curl site averages at 20000 visits weekly. At any given
- moment, there's an average of 3 people browsing the curl.haxx.se site.
- Multiple new authentication schemes are supported: Digest (May), NTLM (June)
- and Negotiate (June).
- November 2003: curl 7.10.8 is released. 45000 lines of code. ~55000 unique
- visitors to the curl.haxx.se site. Five official web mirrors.
- December 2003, full-fledged SSL for FTP is supported.
- January 2004: curl 7.11.0 introduced large file support.
- June 2004:
- curl 7.12.0 introduced IDN support. 10 official web mirrors.

- curl_formparse() function
