I'm not sure this will work at all, but its worth a try
Set your Header to parse php code (in general options), then put this in the header template:
You will also need to put the rest of the header code in that variable, eg:
$header = implode('', file(http://mydomain.com/includes/whatever.cgi'));
As I said before, this probably won't work but I think its worth a try I know implode works with PHP files but have no idea for CGI files.
$header = "<b>this is the header</b>" . implode('', file('http://www.mydomain.com/includes/whatever.cgi')) . "more of the header";
