Questions tagged [mongrel]

Mongrel is an open-source HTTP library and web server written in Ruby.

It is used to run Ruby web applications and presents a standard HTTP interface. This makes layering other servers in front of it possible using a web proxy, a load balancer, or a combination of both, instead of having to use more conventional methods employed to run scripts such as FastCGI or SCGI to communicate.
