NHttp is a simple asynchronous HTTP server written in C# for the .NET framework.

NHttp supports the following features:

• Full request parsing similar to the ASP.net model;

• High performance asynchronous request processing using TcpListener/TcpClient;

• Complete query string parsing;

• Complete form parsing (i.e. application/x-www-form-urlencoded);

• Complete multi-part parsing including file upload (i.e. multipart/form-data);

• Support for parsing and sending cookies.

NHttp specifically does not support any kind of utilities producing output. It for example does not provide a StreamWriter or perform routing. Besides e.g. the Headers and Cookies collections, only the raw output stream is provided. The rest is up to you!

The following shows how to use NHttp:

using (var server = new HttpServer())
{
    server.RequestReceived += (s, e) =>
    {
        using (var writer = new StreamWriter(e.Response.OutputStream))
        {
            writer.Write("Hello world!");
        }
    };

    server.Start();

    Process.Start(String.Format("http://{0}/", server.EndPoint));

    Console.WriteLine("Press any key to continue...");
    Console.ReadKey();
}

Processing requests in NHttp is done in the RequestReceived event. There you have access to the request and response information the request. The example above creates a StreamReader to be able to write text to the response and outputs the same response for every request.

By default, NHttp listens to a random port. Use the following method to specify the port NHttp should listen on:

using (var server = new HttpServer())
{
    // ...

    server.EndPoint = new IPEndPoint(IPAddress.Loopback, 80);

    server.Start();

    // ...
}

This method can also be used to change the interface the HttpServer should be listening to.
