Google for "COMET", you'll get a lot of links. Generally speaking, you want a server framework that can park requests and pick them up when they have data to return. For example, a basic Java Servlet will keep a thread per request, and if you "park" a request (by doing some wait), the thread is suspended along with the request. In this way, you can only have as many clients waiting on a request as you can have threads in the server, which is not enough for big apps.
So, at the very least, you want a system where threads can be reused as requests are paused. As push is becoming popular again, frameworks to https://forum.tuteehub.com/tag/support">support it are blooming, so without more context it is hard to recommend a certain server/framework.
Having said that :-), in the Play Framework (http://www.playframework.org/) there is a https://forum.tuteehub.com/tag/sample">sample https://forum.tuteehub.com/tag/chat">chat application that https://forum.tuteehub.com/tag/uses">uses three variations of "push". If anything, it's worth perusing the code (assuming that you know Java) to get a feel for the various solutions.
