HTTP forward to Pool not working as expected

Give this a shot:

when CLIENT_ACCEPTED {
set default_pool [LB::server pool]
}

when HTTP_REQUEST {
if { [active_members [$default_pool]] < 1 } {
     pool pool_http_sorry_server 
} else { 
     pool $default_pool } }

Insert comments as you wish.

In the client_accepted event, we're setting the variable "default_pool" to the VIP's default pool. Since a user hasn't been mapped to a pool when client_accepted is triggered, this will return the proper default pool.

Then, we're checking whether the default pool has any active members from HTTP_REQUEST and if not, we're sending it to the sorry_server pool.

Finally, I expect you'll need to use OneConnect here to make sure every HTTP Request is evaluated.
