Thanks, Dan. I appreciate your response.

As far as the http_referrer goes, I have two systems hooked up to the same firewall - a PC and a PowerMac. When I access a site that uses http_referrer from the PC, the http_referrer is displayed on the web page as it should be. When I access the same site using the Mac, the http_referrer is not displayed. Alas, there seem to be very few people who know about the Mac. But, that also means that there are very few people who are using Macs, so my problem is not a big one.

On the URL question: I have a site that has multiple domain names framed to the site. I am using http_referrer to display what domain name was used to access the site. When the framed domain name is used to access the Site, the framed domain name appears in the Address bar at the top of the page. Since I was having trouble getting the http_referrer command to work on the Mac, I thought that I may, instead, use the value in the "Address" bar. However, I have no idea how to access this value. Do you know how I could reuse the value in the Address bar on the actual html/php page?

Thank you so much.
