Sending Block Page to user

Thanks alot , This one worked . Now i was simulating that because i wanted to send Block page to users when ASM is detecting Violation instead of Support-ID , will the below be good or the custom predefined block page will continue to besent even with the below :

when ASM_REQUEST_VIOLATION
 {
    log local0. "Violation detected"
    log local0. " [HTTP::uri] "
    HTTP::respond 200 content [subst {
     
         
            Blocking Page
         
             
                We are sorry, but you were blocked due to [ASM::violation_data]  in [HTTP::uri]
                
             
          
    }]
}
