But when does t_relay() itself ever fail due to endpoint reachability issues? I think t_relay() only fails for formal reasons, like host name lookup failure, invalid address format, etc? Otherwise, it returns success; if the endpoint is not reachable, the transaction simply times out. If this is the case, branch route does get called.

my understanding is that t_relay calls a branch route always if t_on_branch is used to set it. then in that branch route, you should be able to call set_forward_no_connect().

I really though that t_relay() fails (return a negative code and doesn't invoke a loaded branch_route) in case the TCP cannot be established. Am I wrong?
