Introducing nComet

nComet is a .NET implementation of the Comet (reverse-AJAX push) architecture. This server-side pipeline uses long-lived client-initiated HTTP connections to push messages to the client. Once the client receives a response, it immediately opens another HTTP request, which the server holds until a message is ready. This architecture allows the server to push dynamic HTML/XML/JSON/etc to the browser, rather than the browser polling the server.

This project focuses on the .NET server-side architecture, initially providing a HttpListener implementation (for a custom host communicating with HTTP.SYS directly) and may eventually provide an ASP.NET implementation as well. The library will simplify the implementation of common message patterns such as pushing latest data as well as sync. Example code for multiple client-side JavaScript implementations will also be provided.
