This depends on how your webserver looks. In some cases it might be applicable to make a listener for regular sockets too.
Otherwise, you will probably have to make your own client. However, you will probably only need to implement the WebSocket transport so it should be fairly straightforward anyway.
For what it's worth I'd suggest looking at the question "Is there a WebSocket client implemented for .NET?" and my (fairly simple) WebSocket Socket.IO transport client implementation for Java.
