Hi,<BR><BR>Exactly how does HTTP Referrer work? I created an ASP page that reads and stores the HTTP Referrer. To test it, I created an HTML page with a link to my ASP page. When I type in the address to the HTML page and then click the link to my ASP page, the HTTP referrer returns "undefined". But when I close the browser; re-open the browser; enter my HTML page from the drop down box and then click the link to the ASP page, I get the correct info in the HTTP referrer.<BR><BR>Why does the HTTP referrer work under some conditions and not others?
