Want to use data group list instead of ip address

Here you go.

class address_list {

host 164.16.1.1

host 164.16.1.2

}

when HTTP_REQUEST { 
   if { [matchclass  [IP::client_addr] equals $::address_list] } { 
     pool f89devl 
   } else { 
     HTTP::redirect "https://outage.vccs.edu" 
   } 
 }

Keep in mind that you can use netmasks in both data groups as well as single IP::addr comparisons.

For example,

when HTTP_REQUEST { 
   if { [IP::addr [IP::client_addr]/24 equals 164.16.1.0] } { 
     pool f89dev1 
   } else { 
     HTTP::redirect "https://outage.vccs.edu" 
   } 
 }

Will validate addresses 164.16.1.[0-255].

You can do the same thing with data groups/matchclass by creating network entries instead of host entries in the datagroup.

Hope this helps...
