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.
