try via $(<reply>hdr(Reason)) in failure route, but be sure that the 402
is the winning reply, triggering the failover route.

Hi Bogdan,
It is in the response coming back to us from the dispatcher endpoint.
In this case, it is an 402 Bad Gateway message, which has a Reason
header with the cause code in it.

Hi Bogdan,
Thanks for the response amd link to append_to_reply()
What is the best function to use to extract the Reason header to
feed in to append_to_reply()?
Thank you.

Hi,
We have a code that response back with a "503 Service not
available" if it has exhausted all the dispatcher endpoints
- see end of email.
It would be useful if we casn send back the Reason header of
the last rejection. Could this be done and what should I
look at?
Thank you!
