I am designing a application where many clients connect to a central server. This server keeps these connections, sending keep-alives every half-hour. The server has a embedded HTTP server, which provides a interface to the client connections (ex. http://server/isClientConnected?id=id). I was wondering what is the best way to go about this. My current implementation is in Java, and I just have a Map with ID’s as the key, but a thread is started for each connection, and I don’t know if this is really the best way to do this. Any pointers would be appreciated.
Thanks,
Isaac Waller

    Use the java.nio package, as described on this page: Building Highly Scalable Servers with Java NIO. Also read this page very carefully: Architecture of a Highly Scalable NIO-Based Server.

    Personally I’d not bother with the NIO internals and use a framework like Apache MINA or xSocket. NIO is complicated and easy to get wrong in very obscure ways. If you want it to “just work”, then use a framework.
