With iRules you can inspect both the content and the status code to determine if you need to re-write the response to the client.

 

 

Do you have the ability to configure your web server to return a ‘503 Service Unavailable’ instead of the ‘sorry’ page? If yes, then I think you are better off checking the response status code rather than digging the content to see if there is an error.

     if {[HTTP::status] >= 500} { 
         HTTP::redirect “http://www.sorry-server.com” 
     } 
 }
