help with irule else test-pool not getting hits

The else statement in your iRule is being used as a case in the switch.

If you want to use an "else" type case for a switch, use the keyword "default" instead of "else" (see the default wiki topic: https://devcentral.f5.com/wiki/irules.switch.ashx).

If you want it to be an else for the first "if" statement, move it out of the switch.

Hope this helps...
