AJAX IRCX客户端和服务器

Question

I am currently developing an IRCX AJAX Chat based system and have a few questions regarding the Server and Client implementation; Any suggestions are welcome:

Server

Should this be implemented as a Web Service, or a Windows Form application? I have experience in developing Windows Forms based servers, however I am wondering if this would be better implemented as a Web Service and if so, why?

Client

How are Web Based Clients implemented today and what is the preferred method to implement a Web Based Client?

My solution so far are

• ASP.NET Web Forms with an AJAX Update Panel (This seems the most viable)
• Using jQuery connecting to the web service with a JavaScript timeout

Polling

How frequently should the server be polled for new messages? 0.5 seconds seems a bit excessive and anything between 2 or 3 seconds seems sluggish.

Thanks for your input.

Answer 1

I believe using ASP.NET (Sockets and an Update Panel) seems to be the best approach. Using jQuery in this context now seems a bit invalid because it would not maintain a persistent state with the Chat Server which is required for Real Time Communication.

An alternative way I found would be using a Web Sockets and Backbone.JS to deal with the data returned from the server.
