Full text of what I was trying to post, below: Hi Paul,
As someone pointed out earlier this week, unless your app is set up so that the only entry point to it is a link from another URL, in most cases your user's entry point into your app would be typing the address directly, in which case there would not be an HTTP_REFERRER. HTTP_REFERRER's most common use is to track marketing and sales data coming from links on affiliates' websites, in emails, and etc. and records the URL of the referring site. So you could determine, for instance, which one of your 10 affiliate sites sends the most customers (and how many each sends), or what percentage of persons you send an email to actually click on your sales link. In your case, if your concern is that you want to ensure that users exit your app, I feel that programmatically closing the browser window would not only accomplish that but be best for security reasons. Or, in the alternative, but way more annoying to users, you can use headers to send them outside your app to another URL. If you programmatically send them back to the logon page, the back button won't then send them to the website they may have previously been on, but back to a previous page in your own app. -- Kristina > Hi Chris , > > I genuinely believe that I have a misunderstanding of what the HTTP_REFERER > is all about.
