Implementing a very small HTTP server in c/c++ and want to use AJAX

I want to have a dynamic webpage that automaticly开发者_如何学编程 updates some information, this information should be received from my c/c++ application using HTTP. I have set up a socket and can send HTML and Javascript files to the browser.

I don't know how to move on. How to encapsulate my data into XMLHttpRequest objects? Or maybe this isn't the way to go? The problem is that my c/c++ application will be run on an embedded system that can't really support php or something like that.

I can't really understand how XMLHttpRequest works, I only find a lot of client examples on the web and not much about how a server should handle it.

A server should handle it as any other request. From the servers point of view, it's a normal HTTP request. Return the data that the client asks for! This is usually a HTML fragment, some XML or some JSON.

Ajax just send normal HTTP GET POST ... request, you should make sure your response header is correct, such as Content-Type.

How do you send information to the browser? The browser is client-side. To get information, you must either query the server (which you say is written in C++). If you want your client to receive request, you should probably emulate a server-like behavior using NodeJS.
