lighttpd a secure, fast, compliant and very flexible web-server which has been optimized for high-performance environments. It has a very low memory footprint compared to other webservers and takes care of cpu-load. Its advanced feature-set (FastCGI, CGI, Auth, Output-Compression, URL-Rewriting and many more) make lighttpd the perfect webserver-software for every server that is suffering load problems.

Nanoweb is a modular Web server written in PHP. It is designed to be small, secure, and extensible.
