Kickoff process by accessing a webpage

Hello,

Is it possible to have my LTM running 10.2.4 access a special webpage once it sees a pool down via an iRule or some other method? But, I don't want to route users to this webpage. This special webpage will kickoff some back-end processes to move the DB function to another data center. My GTM would then also update DNS to move traffic to my other data center at the same time.

Thanks for any help!
