iRule to control snatpool based on destination

Hi Terry,

With just a LC license, you can't actually parse the HTTP as HTTP. Nor can you collect the TCP payload to look for the HTTP headers. So you're limited to making layer 4 based decisions. You can use the class command (matchclass has been deprecated in 10.x) to check the source or destination IP address against an address type datagroup and make a pool and/or SNAT decision based on that. In 10.x, make sure to not include the old format of $::datagroup_name. Here's an example for 10.x:

when CLIENT_ACCEPTED {
   if {[class match [IP::local_addr] equals destination_ips_1_class]}{
       Do something for this destination IP
   } elseif {[class match [IP::local_addr] equals destination_ips_2_class]}{
       Do something else for this destination IP
   } else {
       Take some default action?
   }
}
