Further information
1. A disconnection can only be reliably detected if the remote end of the link has performed an orderly shutdown. As a consequence a return status 2 is not the guarantee that the connection to the client is effectively still valid.
2. A request must always be released by a call to a reply routine ( e.g. httpreply), even after a disconnection has been detected.
