Query SOAP Service from APM to Make Decision

In order to call a service outside the APM, you would need to use an Agent Event and within the iRule that handles that event, you would need to make a sideband request to the service. You'll have to also build the entire request body manually, and parse the response manually, because it doesn't do anything for you automatically except send/receive the data you specify.

In my experience this is not always reliable, and on times I use the sideband command, I'll get timeouts when calling the service (you can change the timeout values however).

Hope this helps.
