That does not work:

The following script fragment:

request_route:
	xlog("Relay: <$ru> via <$du>");
	if (defined $du) {
		xlog("Relay: $$du is defined");
	}


branch_route:
	xlog("Branch: <$ru> via <$du>");
	if (defined $du) {
		xlog("Branch: $$du is defined");
	}


Produces the following log fragment:

Relay: <sip:user at domain:8888;transport=udp> via <<null>>
Branch: <sip:user at domain:8888;transport=udp> via 
<sip:user at domain:8888;transport=udp>
Branch: $du is defined

Let me rephrase the question as it may have been a bit unclear: How can i 
determine within branch_route if the current branch had $du set?
