CL-HTTPis aweb server,clientandproxywritten inCommon Lisp.It is based on its ownweb application framework.It was written by John C. Mallery "in about 10 days"[1]starting in 1994 on aSymbolicsLisp Machine.In the same year a port toMacintosh Common Lispwas done. In 1996 CL-HTTP became the first web server to support theHTTP 1.1protocol.[2]It runs onUnix,Linux,BSD variants,Mac OS X,Solaris,Symbolics GeneraandMicrosoft Windows.

CL-HTTP makes extensive use of theCommon Lisp Object Systemand the macro capabilities of Lisp.[3]

Usage

[edit]

CL-HTTP has been used in several applications. ELM-ART is a tutoring system written in Common Lisp using CL-HTTP.[4] It was later commercialized as NetCoach.[5] InterBook is an early adaptive electronic textbook, also written on top of CL-HTTP.[6] Cl-HTTP has been used very early as a tool to create web interfaces for applications.[7][8][9][10]

In 1994, CL-HTTP was used by theW3Cand other members of theIETFHTTP working group to develop reference clients and servers for HTTP 1.1.[11]

Most prominently, CL-HTTP was used during thepresidency of Bill Clintonas the web server for the White House Publications web site. It distributed the daily press releases and official publications of the Clinton Administration.[12]

CL-HTTP has been used as an example of a non-trivial Lisp application.[13]
