[OpenSIPS-Users] redirect server and paralel forking using registrar module

[Bogdan-Andrei Iancu]

Hi Carlos,

Registrar module, after successfully doing lookup() will push the 
registered contacts into RURI and branches. So you do not need to do 
anything special aside sending the 3xx reply. RURI and branches are 
already populated.

....
if (lookup("location") ) {
send_reply("300", "Redirect");
     exit;
}
.....
