If you're switching pools or pool members based on URI, make sure to add a OneConnect profile to the virtual server. If you're using SNAT set the OneConnect source mask to 0.0.0.0. If you're not using SNAT, set the source mask to 255.255.255.255. For more info check this wiki page:

You could also adapt Bhattman's example to cover the edge cases more clearly:

      pool sorry_page_pool
   } else {
      pool Pool1
   }
}
