[jboss-user] [Remoting] - Re: Is Http Firewall tunneling in Remoting or Messaging ?

[tom.elrod@jboss.com]

Guess the first question is what type of firewalls are you trying to by-pass?  If is just a simple firewall that only allows outbound connections on any port but does not allow inbound connections, can use the remoting multiplex transport which will allow the server to communicate back to the client over the same physical outbound connection established by the client.  

If the firewall actually checks the request header to verify it is indeed an http request, then would be forced to use the remoting http transport.  Can still get callbacks from the server using the http transport, but would have to do using polling, so there would be a slight delay in getting those callbacks.

In the case of multiplex transport, remoting only supports synchronous callbacks at the moment (but are currently working on support for async callbacks as well).
