[jboss-as7-dev] Customising the HTTP Server

We currently have the code for the HTTP server in GIT, what level of changes can be made to this? I don't need to go to the extreme of HTTP session management but I do need something to reliably associate some state with the connection from the client. At the moment I can detect the address is the same as one before but I can't verify it is the same connection. Regards, Darran Lofthouse.
