  Using the <xref:System.Net.HttpListener> class, you can create a simple HTTP protocol listener that responds to HTTP requests. The listener is active for the lifetime of the <xref:System.Net.HttpListener> object and runs within your application with its permissions.
    
  To use <xref:System.Net.HttpListener>, create a new instance of the class using the <xref:System.Net.HttpListener> constructor and use the <xref:System.Net.HttpListener.Prefixes%2A> property to gain access to the collection that holds the strings that specify which Uniform Resource Identifier (URI) prefixes the <xref:System.Net.HttpListener> should process.

+The <xref:System.Net.HttpListener> class is built on top of `HTTP.sys`, which is the kernel mode listener that handles all HTTP traffic for Windows.
+`HTTP.sys` provides connection management, bandwidth throttling, and web server logging.
