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.

Thanks hoolio. I get an error when trying to do the first option below:

 

 

 

01070151:3: Rule [tst] error:

 

line 3: [command is not valid in current event context (CLIENT_ACCEPTED)] [HTTP::redirect "http://adsearcher_testing.target.com/"]

Ah, you caught me! I had a couple of logic and syntax errors in the first post, that I edited shortly thereafter.

 

 

If you test the current rules in my first post, it should work.

 

 

I originally posted an example which was triggered on the CLIENT_ACCEPTED event. If you're using an HTTP command, it needs to be done in an HTTP event. I also left off a closing double quote in the redirect.

 

 

Let me know if you retest using the updated rule above and have any problems.

 

 

Thanks,

Unfortunately this did not work. I point http traffic at the VIP that this iRule sits on from the source address specified in the rule, but the traffic is not redirected at all--it simply passes through to the pool. Any thoughts?
