Update C# WebServer Code

There are many C# WebServer codes, ready to use, out there, but i need a C# WebServer multi-thread. It must be multi-thread, which means, it must be able to serve multiple pages and files, including video, at the same time. Here is an example of a ready to use webserver: [login to view URL] It's a copy and paste code, it works perfectly, but it's not multi thread. It gets stuck to each request until its finished. I need something like exactly this code, but multi-thread. Waiting for proposals.
