[OpenSER-Users] newbie help - handeling 302s and 404s

Or rather (as you've pointed out yourself), from

*## ANYTHING ADDED BELOW CAUSE OPENSER TO CRASH ???####

route[5] {
       rewritehostport("**10.10.10.10:5060 * <http://10.10.10.10:5060/>*");
* *       t_on_failure("1");
       route(1);
       exit;
}*

If you follow the logic, looks to me like it's 'exit-ting' twice. First call
jumps to route[5], then within route[5] you've also callled the
*route[1]* sub-routine
- which also contains an 'exit',  so from within *route[1]* it never returns
to *route[5]* as you've intended.
