F5 iRule for persistence with header and source address persistence as fallback

Hi eLeCtRoN , 
I have a bit poor environment to test my script for you , so sorry for that. 

I have written this script for your case , Find it : 

when HTTP_REQUEST {
   if {[string tolower [HTTP::host]] starts_with "company.com"}{
      if {[string tolower [HTTP::uri]] starts_with "/human"}{
         pool "pool_human"
      } elseif { [string tolower [HTTP::uri]] starts_with "/body"}{ 
        if {[HTTP::header "xxx"] contains "header_1"}{
         pool "pool_body" member 10.10.10.10 80
      } elseif {[HTTP::header "xxx"] contains "header_2"}{ 
         pool "pool_body" member 10.10.10.20 80
      } else {
      pool "pool_body"
      persist source_addr 255.255.255.255 3600  
      }
      
       } elseif {[string tolower [HTTP::uri]] starts_with "/dev"}{
         pool "pool_dev"
      }
   }
}

> For "/body" conditions , I have added a new loop For pool members selections and persistence as well.

( 10.10.10.10:80) or (10.10.10.20:80) are for examples to test the validity of my iRule script , you need to change both of them to " Pool_body" members ips and port , okay? 

> this line ( persist source_addr 255.255.255.255 3600 ) to make source address affinity persistence as a fallback ip the the first and second conditions fails , Mask " 255.255.255.255 " is to make persistence by ip not subnet , you can specify subnet if you need that , Also "3600" attribute means the duration that Big-ip stores the source ip in persistence record table . 

try it and give me your feedback , I will try to simulate this environment on my lab to see.
