I usaully use a URI forwarding policy to direct traffic based off URI. You can setup a different pool, with whatever port you want, for each special URI and use the virtual server's default pool for all other traffic

Local Traffic >> Policy
Rule X: HTTP URI path starts with /X Forward traffic to pool testsite.uri.X
Rule Y: HTTP URI path starts with /Y Forward traffic to pool testsite.uri.X

Thanks Jason. That does seem more efficient. I haven't ever messed with policies to be honest. However, I'm guess the configuration would look something like this (we are running 11.6 code):

 

Policy
   Strategy: First-Match
   Requires: http
   Controls: forwarding

Rules

  Conditions.
    operand: http-uri
    event: request*
    selector: path
    condition: equal (or contains)
      */X
      */Y

  Actions
    Target: Forward
    Event: Request
    Action: select
    Parameter: pool (POOL-ABC)

Does that look correct based on your experience?

 

Thanks in advance!
