In Apache - at least with 1.3 a few years ago - CGI.SERVER_NAME returned the value in the ServerName directive no matter which virtual host was being accessed. This may have been changed by now. CGI.HTTP_HOST, on the other hand, correctly identified the host being accessed. That said, I'm not sure what you mean by a more robust alternative. ~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:256997 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4

RE: Apache, IE cgi.http_referer
Possibly a privacy setting, or, again, make sure you don't have any software running (anti-virus, firewall, antispyware, an add-in toolbar etc.) that has a feature that's scrubbing the referrer info. It's possible that software would only support/effect IE, and is leaving Firefox untouched. Honestly though, the conclusion you probably should be coming to here is not to depend on the referrer info being present for anything meaningful, since there are a lot of things a potential user could have installed, or ways a browser might be set, that can interfere with it. -Original Message- From: Matt Williams [mailto:[EMAIL PROTECTED] Sent: Monday, October 16, 2006 10:47 AM To: CF-Talk Subject: Re: Apache, IE cgi.http_referer On 10/16/06, Snake [EMAIL PROTECTED] wrote: Any variable that is considered personal information and can be used for tracking purposes may not be sent.

Okay, sorry for ignoring the comments that I shouldn't be relying on the referer. This is a system where there is some control over the user's browser. It is online software where certain requirements can be met. However, I tried adjusting both the security and privacy settings but no help. Also, there isn't any firewall or other software blockage. This is just my local machine. So the question at hand should be how can you make a link that will go back one page (that page being unknown) and refresh it?

Re: Apache, IE cgi.http_referer
By unknown I simply meant that it could be one of several possible pages within the site. So yes, all potential pages are internal and we do have control over those. A littel more detail... The initial page has a drop down select box. In the on change of that select I redirect to another page with a form. If the user is to click cancel on that form, I want to take them back one page, but the select box should have it's original value (originally came from db) selected and not the value the user selected which caused the redirect. Make sense? So it is a select box which could be wrapped in form tags and then a hidden field passed. I was just looking for something better. Thanks.
