Traffic Policy forwarding behavior when pool is down
Hello folks. Would someone be able to explain the behavior of a Traffic Policy when a pool is down.
For the scenario:
I want to create a single virtual server that hosts multiple websites.
Each website is hosted on separate clusters of virtual machines. The hosts in the cluster for example-1.com are in pool_example1, and the hosts in the cluster for example-2.com are in pool_example2.
I create a traffic policy that checks the HTTPS Host for the FQDN and then steers example-1.com to a pool_example1 and example-2.com to pool_example2. I also create a rule to match all traffic with the action to reset the connection to catch everything else. A default pool has been set on the Virtual Server.
There is a health monitor in pool_example1 monitoring the nodes. If all of the nodes in pool_example1 are down, and the health monitor marks it down, what would I expect to happen if I tried to navigate to example-1.com? Is the traffic policy aware that the pool is down? Would I get the default pool? Or would I hit the catch all I built in the traffic policy and get a RST? Or would something else happen?
Thanks!

Hello zack_olson
Policy will still send your request to pool_example1 and will be reseted cause there will be no healthy members.
If you want to check pool active members before making a decision you should go with irules.
There are plenty of examples online.
