I've read I can try to read from the socket, but in HTTP the client sends the request, and doesn't write any more to the socket.

Probably you can try to write back to the socket, and check if this operation fails?

You would pretty much need to fill up the socket send buffer before it even thinks about failing. You might consider doing a test to see if attempting a non-blocking read on the socket yields a pending read. For blocking reads, this would result in an EOF if the client has dropped the connection, but I'm not sure what will happen w/ the non-blocking reads on your system without running a little test. Jon
