http redirect irule issue

If a client makes multiple requests over the same TCP connection, subsequent requests will not necessarily be sent to the default pool. It's always better to specify a default (or "else") clause in the iRule if you're selecting a pool. You can do this without hardcoding the name of the default pool:

 
 when CLIENT_ACCEPTED { 
  
     Save the name of the VIP's default pool 
    set default_pool [LB::server pool] 
 } 
 when HTTP_REQUEST { 
  
    if {$some_condition==1}{ 
       pool pool_1 
    } elseif {$some_other_condition==1}{ 
       pool pool_2 
    } else { 
        Use the VIP's default pool 
       pool $default_pool 
    } 
 }
