Kayak

Kayak is a lightweight HTTP server+framework. Written in C#, it has been carefully designed to be true to the protocol it implements, get out of your way, and not tell you how to live. It is easy to integrate into a variety of applications, and is an excellent choice for creating interactive websites and web APIs. Whether your coming from ASP.NET, PHP, Django, or elsewhere, you’ll find Kayak to be refreshingly simple to use.
