Optimized chat server protocol for server side scripting languages

Nowadays using comprehensive Web chatting is a very popular feature in Websites. Most of the Websites use server-side scripting languages to deliver dynamic web pages to their users. The problem of implementing a chat server with these languages is that there are no long running processes to establish a firm long lived socket connection with the server. Therefore, when the server needs to send some information immediately to the web client, there should be a mechanism to do so. In this paper, we discuss our protocols and optimizing techniques for such kind of server-client environment. The target of this project is to use our protocol to design and implement an optimized Web chat client and a server using a server side scripting language.
