Hi DarkSide,

 

 

You can use HTTP::respond to send a specific response code and append a list of header names and values. I think something like this should work:

 

 


when HTTP_REQUEST {

    Check if the User-Agent header 
   if {[HTTP::header User-Agent] contains "some user-agent string"}{

       Send a 503 response with a Retry-After header set to 5 minutes
       Don't include the Server: BigIP header (noserver)
       Retry-After described in: http://tools.ietf.org/html/rfc2616section-14.37
      HTTP::respond 503 noserver "Retry-After" 300
   }
}
