lighttpd (prescribed pronunciation: "lighty") is an open-source web server optimized for speed-critical environments. It was originally written by Jan Kneschke as a proof-of-concept of the c10k problem – how to handle 10,000 connections in parallel on one server, but has gained worldwide popularity. Its name is a portmanteau of "light" and "httpd".
