mathopd

Very small, yet very fast HTTP server

Mathopd is a very small, yet very fast HTTP server for UN*X systems. Mathopd supports useful features of HTTP/1.1, such as persistent connections, partial responses and pipelining. It does not support things like content negotiation. It also supports CGI/1.1. Mathopd was designed specifically to run as a single process, and to never grow in size. When this software was first written (early 1996) this was something that other HTTP servers were not very good at.
