Is is possible to make a client to client connection with HTML5

I know that HTML5 has the new feature called WebSockets for making a connection between browser and server.

But is it possible that the server helps clients make a connection between them?开发者_Python百科

I want to transfer file from client A to client B

No, WebSockets don't (yet) help in this instance, because browsers only support the client half of the protocol.

It's certainly possible to have a central WebSocket server responsible for relaying messages between any set of clients, though.
