lighttpd (pronounced "lighty") is an open-source web server optimized for speed-critical environments while remaining standards-compliant, secure and flexible. 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".
The low memory footprint (compared to other web servers), small CPU load and speed optimizations make lighttpd suitable for servers that are suffering load problems, or for serving static media separately from dynamic content. lighttpd is free and open-source software and is distributed under the BSD license. It runs natively on Unix-like operating systems, as well as Microsoft Windows.
lighttpd supports the FastCGI, SCGI and CGI interfaces to external programs, allowing web applications written in any programming language to be used with the server. As a particularly popular language, PHP performance has received special attention. Lighttpd's FastCGI can be configured to support PHP with opcode caches (like APC) properly and efficiently. Additionally, it has received attention from its popularity within the Python, Perl, Ruby and Lua communities. Lighttpd also supports WebDNA, the resilient in-memory database system designed to build database-driven websites. It is a popular web server for the Catalyst and Ruby on Rails web frameworks. Lighttpd does not support ISAPI.
Lighttpd is used by a number of high-traffic websites, among them are Bloglines and xkcd. It was used in the past by Meebo and YouTube.[better source needed] The Wikimedia Foundation also runs Lighttpd servers.
all of these describe lighttpd (pron. lighty).
LightTPD webserver for Windows Systems.
lighttpd is used by many well-known sites. The typical scenario is using lighttpd as off-load server to push out static content and leave the complex work to another server.
