CL-HTTP has been used in several applications. ELM-ART is a tutoring system written in Common Lisp using CL-HTTP. It was later commercialized as NetCoach. InterBook is an early adaptive electronic text book, also written on top of CL-HTTP. Cl-HTTP has been used very early as a tool to create web interfaces for applications.
In 1994, CL-HTTP was used by the W3C and other members of the IETF HTTP working group to develop reference clients and servers for HTTP 1.1.
Most prominently, CL-HTTP was used during the presidency of Bill Clinton as the web server for the White House Publications web site. It distributed the daily press releases and official publications of the Clinton Administration.
CL-HTTP has been used as an example of a non-trivial Lisp application.
