[jboss-user] hitting a specific node from the cluster

Hello guys, Just new to JBoss World so if this is not the right list please be kind and advise where should I post the question. Currently we have a cluster formed of three nodes, each of them in separate machines. I want to be able to target a specific node from my HTTP request. Is there any HTTP Header/GET/POST param that would allow me to make one node respond to my request? Thanks in advance, -Nestor
