[SR-Users] Accessing received after lookup()

[DanB]

Hey Daniel,

Yeah, got the header out of received from path. Actually I have 
de-coupled registrations which work and store just fine the received 
parameter out of INVITEs which are querying the registrar using lookup. 
In the end I have ended up using received parameter if present in $du 
after lookup and appending it to contact (removing it after in the proxy 
which sits in front of registrar). Here is the code snippet for anyone 
needing it in the future:

"""
	if (!lookup("location")) {
		$var(rc) = $rc;
		t_newtran();
		switch ($var(rc)) {
			case -1:
			case -3:
				send_reply("404", "Not Found");
				exit;
			case -2:
				send_reply("405", "Method Not Allowed");
				exit;
		}
	}
	# Populate received contact parameter if found in db
	$var(received) = $(du{uri.param,received});
	if !strempty( $var(received) ) {
		$ru = $ru + ";rcv="+ $var(received);
	}
	sl_send_reply("302", "Locator Redirect");
	exit;
"""

Thanks,
DanB
