Clear cache?..

[zzz]

I have a script that updates an image but saves it with the exact same name. When I retun back to a page that displays the image, it shows the old one untill I refresh the page.

Is there a way to clear the cache before I get back to the page, perhaps on the pge that processes the update?..

Holding down F5 and hitting refresh clear's the cache

Uhm.. F5 is the refresh button. Why do you need to hold it down? 🙂
Press CTRL+F5 to clear the cache and refresh.

I don't want to ask users to refresh the screen to see the change, I'd like to return screen refreshed already.

I assume I can do something like this with META tags, but is there a way in PHP?

Well you could do it like:

header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);

..but that will refresh everytime althought files have not been changed. There is an option for that but I just cant remember how it went..

I suppose I can append a var to the redirect URL and if (isset($_GET['myvar'])) input these lines...
