Redirection based on referring URL

Copy linkTweet thisAlerts:
Nov 14.2005

I’m trying to find a code that will redirect a user to a login page if they are trying to access a page within a certain directory of our website from outside of that directory. Basically, if the page they came from isn’t within [url]http:///www.mysite/catalog/[/url] , they should be redirected. I found some codes that cover if it isn’t coming from a specific page…but I need it to be anything within that directory..

Thanks for any help in advance!

@UltimaterNov 14.2005 — document.referrer contains a string, blank in some cases becase of browser settings etc, that the user came from. I'd suggest sending a "get" method parameter over to your other page, and reading it with JavaScript to figure out where to redirect them to. You could even do this in PHP and serve users with JavaScript disabled by reading parameters.

Here's an example showing how JavaScript can read the querystring:

Success!
