[FX.php List] [OFF] Reload page in Safari after back button?

[Bob Patin]

Joel,

I never have found a solution for this nagging problem; no matter whether you tell users not to use the BACK button, they do it anyway… 

I was thinking about setting a session var that would keep track of where the user is *supposed* to be, but when you use the BACK button it doesn't actually reload the page, so there's no way to look at the session var and see if action needs to be taken.

My question would be this: is there anything, PHP or Javascript, that would be triggered when someone arrives at a page using the BACK button?

If you solve it you'll be my hero--wait, you're already my hero!

Bob

(e.g.: Echo some $_SESSION vars on page1, update those vars on page2, then click the Back button.  In Safari, page1 still shows the original vars until you click Reload.  All other browsers show the updated vars as soon as you click Back)
