[OpenSIPS-Users] Getting header from 302

Yeah, my thing is when i use the failure route i can in theory grab the
response header and ignore the 302 and send to the invite route again to
actually send the call out via do_routing.
What I'm trying to do is:
- On receiving an invite: forward to an endpoint.
- This endpoint will simply reply with 302 including a header.
- I want to grab that header and continue routing normally (do_routing)

I could do that with the failure route, but not so sure about the onreply
route.

Regards,
