hello,

You should have an irule like that:

if {$host contains "app1"} {
     condition
} elseif {$host contains "app2"} {
     condition
} else {$host contains "app3"} {
     condition
}

The else should not be conditional, so either use elseif again, or remove the condition in your else.

if {$host contains "app1"} {
     condition
} elseif {$host contains "app2"} {
     condition
} else {
     condition
}

if my answer don't resolve your problem can you give me your irule in order to check it.

Regards
