Sending requests to specific URI to different pool based on load
I'm trying to setup a parking lot feature where clients are sent to a maintenance page pool based on load or connections to a virtual server.
For example:
requests to http://www.domain.com/start and http://www.domain.com/stepX normally goto Pool A
When load or connections count gets to a threshold send requests to http://www.domain.com/start to Pool B but all other requests like http://www.domain.com/stepX to Pool A.
When load or connections count drops below threshold, send all requests back to pool A.
Is this possible? I'm running BigIP version 9.4.5. I looked at trying to do this with health monitors, but using pool health monitors would take the entire node offline. I'm looking at just alleviating some of the load by redirecting a specific start URI to another pool.
Thanks.
