Hi Arjun,

Are you applying this iRule to a port 80 HTTP VIP? If so, can you try this? 

when HTTP_REQUEST {
   log local0. "[IP::client_addr]:[TCP::client_port]: [HTTP::method] request to [HTTP::host][HTTP::uri]"
   if {[HTTP::path] contains "BluePortServlets/PaymentPortal" }{
      log local0. "[IP::client_addr]:[TCP::client_port]: Dropping request to [HTTP::uri]"
      drop
   }
}

Once you're done testing, you can comment out the debug logging.
