Hello guys,
Is it possible to call a failure_route like a normal route?
i.e.:
{
t_on_failure("myroute");
}
...
route("myroute");
failure_route[myroute] {
...
}
Let me explain:
I have this scenario where a DNS name may get deleted and a dns resolution
will fail. There's no pinging to that gateway so i need to:
- skip that gateway when dispatching to the setid
- detect whether the domain is up and available
And failover to the next gateway.
I don't know of any other way so on the DISPATCH route, I'm doing:
route[DISPATCH] {
# round robin dispatching on gateways group '1'
if(!ds_select_dst("1", "4")) {
send_reply("404", "No destination");
exit;
}
xlog("L_DBG", "--- SCRIPT: going to <$ru> via
<$du>\n");
if(dns_query("$du", "xyz")) {
t_on_failure("RTF_DISPATCH");
route(RELAY);
} else {
route(RTF_DISPATCH);
}
exit;
}
to try to resolve and if it fails, it will just go to the failover route.
makes sense?
