mapclass2node

It's pretty simple, though not configured quite the same as the select statement on the pool. Here's what to do:

 
 class node_class { 
    "s1s1 10.11.1.10:80" 
    "s1s2 10.11.1.20:80" 
 } 
  
 rule direct_select { 
    when HTTP_REQUEST { 
       node [findclass [HTTP::cookie "server"] $::node_class " "] 
    } 
 } 
 

The findclass command does pretty much the same thing as the mapclass2node, returning the latter portion of the matched class entry. The node command directly selects the node.
