SPUG: Error message

Wed May 15 09:50:04 CDT 2002

Thanks for responding to my request Don. I would like to get rid of the
HTTP_REFERER. However, when I do, the script continues to send emails to the 
receiver and continues to do so until the sender hits stop on their browser. 
How can I get rid of the HTTP_REFERER and still have the script perform as 
intended (i.e. send only one email?) Thanks!
