- Fast failover.
After t_relay, the destination should be tried for max 2 sec per host. No maximum for the whole set. Thus, if a destination has 4 SRV records, and each host fails after 2 secs, a 408 will be sent back after a total of 8 secs. If a (proivisional) response arrives within 2 sec, a 408 MUST NOT be sent.
What I have now is when I set fr_timer to 2 secs, I always get a 408 if the 1st host id down, even if I receive a response from the 2nd host in the SRV.
