You've got some basic syntax errors and you're missing the Event HTTP_REQUEST. Now as for your use of TCP close and Event Disable i'm not 100% on whether they can work together. Need to test that. Anyway something like this?

 

when HTTP_REQUEST
 if { [active_members My_DEV_443_Pool] < 1 } { 
     HTTP::respond 503 content "Page is currently unavailable.The system is unable to fulfill your request. This is not a problem with your computer or network connection.:\" 
     event disable 
     TCP::close 
     }
