You alter/assign referrer, either in perl scripting or browser plugin.

Yes, but that does not matter. The idea is that $ENV{'HTTP_REFERER'} is set to some nonsense only if running as CGI. Unfortunately, this is not entirely true. Clients can choose not to send a Referer header, so you might run a CGI with $ENV{'HTTP_REFERER'} not set. Using $ENV{'GATEWAY_INTERFACE'} should be reliable. It is set by the webserver, it is always set, and it is set to a constant value independent from the HTTP request.
