Lighttpd is a web server and load balancer optimized for speed-critical environments products while remaining standards-compliant, secure and flexible. It is used by many high-traffic websites, including Youtube. Lighttpd supports dynamic HTTP content such as PHP scripts using the FastCGI interface.
