Remember each pages referring page.

Hi All,

I need a script (triggered by body onLoad) that will store and display in an alert box, the url of the previous page to the one displayed. That is, I need to know the url of the page that called the one currently on the screen.

I know that document.referrer is not reliable across all versions of IE and that you can't get at the 'History' function anymore.

If any one can come up with a javascript/javascripted process to solve this one, they would have a good site access security product that people would pay for.

Any idea's?

Regards

Gary

It's nothing to do with IE per se, it's just that browsers and proxy servers can be configured not to send referer information with requests. There isn't a workaround - if referer information isn't there there's no process that can get it.

What do you really want? If you're looking to validate a mailform or something like that, PHP or ASP session validation is probably your best bet.

btw - I deleted your other thread which was almost the same as this. Please don't start multiple threads on the same subject.

Hi Brothercake,

I need to make sure that the visitor to the site enters from the front page and cannot view a subsequent page by having bookmarked it on a previous visit and 'jump' straight in. As 'referrer' and 'history' are not suitable, how can I store the current pages URL so that the next page can test if the referring page is acceptable?

Regards

Hi Glenn,

I started with request.servervariables("HTTP_REFERER") but the problem is that it is not always available, or am I doing something wrong (like trying to becone a programmer!).

Cheers

the reason for that is what brothercake mentioned in his first post. Use session validation instead of checking referrer.

So you have to establish a session on your front page. On subsequent pages you check for that session variable, and if it isn't there do a redirect or whatever.
