How do u make a page reload if u hit the back button?

sprockett

What i love about vanilla is that when i hit back button, the previous page loads entirely from scratch.... How is this done? I am coding a photogallery, and when a user submits an image, and hits back button, i want it to refresh so he see's his loaded photo... How does vanilla do it? Thanks!

i tried using pragma nocache, but that doesnt work.. :(

I think we need to distinguish server-side caching and client-side caching.

Oops.. sorry i wasnt more specific, i mean client-side caching.. basically, just like vanilla, if i hit back button, the browser should send in a request to the server.... Right now for my own script, it just loads it from the browser cache...

On IE you need to add

<META HTTP-EQUIV="Expires" CONTENT="-1">
too

Take a look at appg/headers.php

browsers are dumb

it's all in the headers, when the form submits, it submits your data to this thread assigning it this ID (for this thread) then calls headers to refresh this thread instead of sending you elsewhere. While you could just as easily get thrown back to anywhere else you wish depending on the actions you assign to that header file

This is what I use. It's perfect, <?php header('Expires: ' . time() - 1000); header('Pragma: private'); header('Cache-Control: no-cache, must-revalidate'); ?> OR <?php function DisableCache() { header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); header("Cache-Control: no-store, no-cache, must-revalidate"); header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); } ?>
