Hi Atul,

It depends on your requirements.

If you need to be able to handle "forking" scenarios then
this cannot be handled with a just stateless proxy.

For forking, you need a stateful proxy because the proxy
will have to remember the multiple destinations that the call
was forwarded to.  It has to decide which responses to forward
and to be able to CANCEL some or all of the forked calls.

Regards,

Attila
