问题 I want to implement a chat system for my site. The functionality will be very similar to facebook chat. The chats will be one to one based. I know how to build the chat system using PHP, MySql and using JQuery. But my concern is that it won’t scale to large number of users in the long term.

This will cause extra load on the server as the user base

问题 I'm trying to implement comet in my ASP.Net MVC 2.0 project. I'm using WebSync from FrozenMountain. My website is coded in C# 4.0 and ASP.Net 4.0.

I used the technique of creating an XMLHttpRequest Connection and keeping it open all the time so the server can continuously push data to all the clients connected whenever it is available. My client side code

问题 I'm trying to implement a very basic chat/echo web page. When the client visits /notify:8000 a simple site loads, on the client side a request is initiated to establish a listener, on the back-end the cloud count is updated and sent to all existing clients.
