irule help - disable persistence

[Ashu_Aggarwal]

I have a VS configured with session cookie persistence profile. So all the requests from users & middleware receive session cookie. users receives session cookie is fine but all the requests from middleware routed to only one server in load balancing pool which is not desired. I need to configure a irule so that all the POST messages from middleware should not receive a cookie & get loadbalanced more efficiently. This is the i-rule i came up with. Would it work ?

when CLIENT_ACCEPTED {

     switch [IP::client_addr] {

       "10.27.15.231" { persist none }

       "10.27.15.236" { persist none }

       "10.27.15.238" { persist none }

       }

   }

That should work, although you might want to create a data-group of type address, and use class match

when CLIENT_ACCEPTED { if {[class match [IP::client_addr] equals "middleware-ip_dg"]} { persist none } }
