I would REALLY appreciate if someone could answer the
following
questions for me.
1. What is the definition of a 'negative' result in relation to
t_reply()? I am seeing situations where t_relay() seems to think that
407 Proxy Auth is a negative result, because a previously set
t_on_failure is executing when it connects to the gateway
sucessfully.
AFAIK every response with response value >= 300 will trigger the failure
route.
2. Under what circumstances does t_reply() return 0,
and under what
circumstaces does it return -1? Seems like it always returns 0, no
matter what happens.
no glue. check the source code.
T hink I do not get your setup right. What do you want to achieve? If
you use t_reply, you should not setup a failure route.
3. When t_relay() fails to connect to a gateway, if
t_on_failure(N)
had previously been set, where does execution jump to
t_on_failure(N)? It isn't right after t_relay() returns, and it isn't
_within_ t_relay, so where is it? Is it at some arbitrary point? Is
it after the current route() block ends?
The current route block will be executed until the end of the route
block or exit/return. (As without using t_on_failure)
Then, typically some seconds later, when the failure happens, the
transaction enters the failure route.

Thanks, Doug.
