Thanks so much for your response, but unfortunately this doesn't help.

 

I already have that exact code in HTTP_REQUEST, but [active_members] doesn't work immediately after a pool goes down. It takes some time after the last pool member goes down, until the pool is marked as unavailable. During this short period, the LB_FAILED method is triggered.

Any ideas are greatly appreciated.
