eslimeHTTPserver is an experimental WebServer written by me, Alberto Navarro.
I wrote this because I needed custom HTTP server/CGI client for test some things for an university project. I licensed all work under LGPL license.
At the moment, eslimeHTTPserver is in alpha status, and only supports CGI, but I'm working for add support for FastCGI, SCGI, VirtualHosts, Auth, Output-Compression, URL-Rewriting, Logs, CommandLine configuration, etc...
