[SR-Users] Quick Question

[Geoffrey Mina]

Definitely not adding it back anywhere.  Is it possible that loose_route()
or t_relay() would add it back?  These are the relevant blocks of code this
call is traversing.

xlog("L_ERR","We have a Proxy Route request, performing loose routing to
end point [$(hdr(Route))]");
remove_hf("P-Proxy-Route");
remove_hf("Route");

if(loose_route()){
               route(RELAY);
}else{
                sl_send_reply("404","Unable to route request");
}


route[RELAY]{
    xlog("L_INFO", "Setting up reply handler and relaying request\n");

    t_on_reply("LOG");
    if(!t_relay()){
        sl_reply_error();
    }
}
