Redirect to VIP based on source IP

If you want to redirect a single client to a different URL (or VIP), you can use a rule like this:

when HTTP_REQUEST {
   if { [IP::addr [IP::remote_addr] equals 10.0.0.10] } {
      HTTP::redirect "http://my.vip.example.com/"
   }
}

Or if you want to make the decision based on multiple hosts or networks, you can use a class (called a datagroup in the GUI) and a rule that references it:

Datagroup definition:

class my_hosts_networks_class  {
   network 10.0.0.0 mask 255.0.0.0
   host 192.168.0.100
}

And rule:

when HTTP_REQUEST {
   if { [matchclass [IP::remote_addr] equals $::my_hosts_networks_class] } {
      HTTP::redirect "http://my.vip.example.com/"
   }
}

Note: to create the datagroup in the GUI, navigate to Local Traffic >> iRules and then click on the Datagroup tab. Enter the hosts/networks in the datagroup and then create the rule which references it.
