Hallo Dear Everyone,

How can I create a connection between client and server, rather than using TCP/IP(Socket)?
I have heard that is possible, posting and getting messages from a given URL. For example, consider there two machines, MachineA and MachineB. MachineA has to always check for an incoming message on at a given URL, and MachineB sends or puts a message on that given URL. This has to work in vice versa, MachineA may act as MachineB and MachineB may act as MachineA.

I think it is possible to use the HttpListner class for such problem.
Is that possible?

Thank You

While Nishant Sivakumar has provided an excellent answer, you could also take a look at:
MessageQueue[^] - the .Net interface to MSMQ.

Take a look at MessageQueue.BeginReceive[^] - depending on what you are doing, this might be both more flexible, and easier to implement.

Using MSMQ with WCF is also an option...

I know a webpage where there is a solution like that wether i don't know if it is using TCP/IP or not.

Hope it is helpful

You can do this via WCF. MachineA subscribes to a callback service on ServerC. MachineB connects to ServerC and periodically sends messages, and MachineA automatically receives them via the callback.

[Update]
--------------

In response to your updated question, while you can use HttpListener, now you would not automatically get callbacks (which is there in WCF). And WCF supports HTTP protocols too for communication. So there's no real need to avoid WCF. But if you don't want to go the WCF route, you can write your own server app, except that the client machines would either need to poll the server or you'd need to implement some kind of thin listening server on each client to simulate/facilitate a push based callback mechanism.
