Hi folks,
The rfc says to restart timer C on every provisional response received,
but what about the failures according to rfc3263.
Chapter 4.3 says that on fatal transport error, or reception of a 503,
or txntimeout w/o any provisionals, one should create a new txn and
send the request to the next server selected from the DNS-data available.
Do I update Timer C, when I create this new txn?
If I do, this could keep a proxy going for a very long time, if a lot of the
servers dns is pointing to, answer very slowly with 503s. Or just a lot of
consequtive transaction timeouts to each server in the DNS-list.
Naturally it would require a big list of choices in the DNS, since txns timeout
after normally 32s, but I always saw the timer C as a protection for making sure
the proxy doesnt keep trying to long, so I wouldnt want to restart it in these
cases.
