How to send file from server to multiple clients at a time in mfc using sockets?

I am making simple one on server side & one on client side application for transfering file from one location to an开发者_StackOverflow社区other location or from one computer to another computer if computers are in network.

I used the code from http://www.codeproject.com/KB/IP/SocketFileTransfer.aspx. It is working & file transfered successfully.

But i need to transfer file from server to multiple clients at a time. I mean on server, there should be more than two client can connect & they can receive file at same time.

I don't know how to maintain queue for that & how to pass CSocket object to method using Threading & any other way.

I also don't know how to prepare queue of CSocket objects.

So, please if you have any solution or alternative way then please tell me....

Creating thread for each client will transfer file to each client at a time.
