Using matchclass to check Source IP with HTTP_REQUEST?

If you aren't and don't plan to add other iRules to this VIP, you could replace the pool_selected variable logic and just disable the HTTP_REQUEST event for clients who are in the datagroup. This would apply to all iRules on the VIP though.

 
  when CLIENT_ACCEPTED {  
    
      Check if the client IP is in the testips datagroup  
     if { [matchclass [IP::client_addr] equals $::testips] } {  
    
         Select poolA 
        pool poolA 
  
         Disable the HTTP_REQUEST event for this TCP connection as it isn't needed 
        event HTTP_REQUEST disable 
     }  
  }  
  when HTTP_REQUEST {  
    
      Check the requested path  
     switch -glob [HTTP::path] {  
    
        "*/cf/*" -  
        "*/hf/*" {  
           pool poolB  
        }  
        "*/asweb/* {  
           pool poolC  
        }  
        "*/vh/* {  
           pool poolD  
        }  
        default {  
           pool poolE  
        }  
     }  
  }
