Marc and HTTP_REFERER

Hello, 

I've got a little problem with Marc, and since I can't reach the author, I ask
my question here if someone has encountered the problem. When I launch
marc-search.cgi with my web page, I've always got this error : 

Sorry, your client needs to set HTTP_REFERER This error occured in the main
package of /home/httpd/cgi-bin/marc-search.cgi at line 80

Do you know HTTP_REFERER and what value I have to give it?

Thank you
