Using iRule to redirect F5 traffic

Maneesh thanks for your suggestion. Now will this work even if the pool members are still active and passing Health checks?

I also want to provide clarification that this keyword resides within the following URL site http://abc.home.com/home/a/b/Offline.html

So when the above site is accessed it will display Online for normal traffic flow or Offline which then requires me to redirect the traffic over to URL http://www.example.com:1010/Maintenance.htm
