Ace optimization bypass

Answered Question
Nov 30th, 2009

Dear all,

I am trying to find a way to bypass optimization for a specific L7 Class-Map on ACE 4710. My problem is that i am using one VIP and i am intercepting users based on L7 URL match statements and send them to the apropriate sticky-serverfarms (many http-https applications on the same domain name URL). Thus, when i apply my optimization Policy i apply it on the VIP class-map under multimatch policy. I am looking for a way to exclude optimization for a certain L7 class-map eq(if users hit  ".*/nooptimization/.*" then they should not be optimized).

waitting for your reply.

I have this problem too.

policy-map type optimization http first-match Gilles_AVS
  class dynamic_content_map
    action dynamic_content
  class object_map
    action object parameter HTP
  class ff_object_map
    action opt-images
  class web_html
    action web_html
  class avs_default_map
    action avs_default

policy-map multi-match AVS
  class VIP-15-80
    loadbalance vip inservice
    loadbalance policy LB1
    optimize http policy Gilles_AVS
    loadbalance vip icmp-reply active
    nat dynamic 1 vlan 30
    appl-parameter http advanced-options cisco_avs_parametermap

One policy for loadbalancing and one policy for optimization with class-map inside the optimization policy to define what optimization for which url.

This should work.

Gilles.
