At the time OnClientCreate is called, the socket is not assigned yet to the
connection. So it is not easy to cancel the connection.
OnClientConnect is a better place. From there you can call Shutdown to
terminate the connection you don't want.

Hello Guys !
I'm considering the option of pushing ICS to SourceForge and I would like to
have your opinion.
Does someone already have a real experience of SourceForge as a developper ?
The first decision is should I select CVS or SVN ?
Any advice appreciated.
