[RESOLVED] header(Location redirection

[spetsacdc]

Hello, I have a page that updates a user's profile picture (replacing the old one) and redirects them back to their profile.

I use

header('Location: /control_panel.php?f=users');

to redirect them after the new image is saved.

Now, the problem is that the profile page often shows the old image before they refresh the page. I'm guessing this is because their profile picture always has the same name (their user_id.jpg). So, if you are user #152 your picture is 152.jpg.

Is there an easy way to make sure the image is always reloaded from its source and not from cache? Or, will I need to always change the file name to like user_id_random_number.jpg

If I have to have the file name as user_id_random_number, I don't know how to make my existing code work because I use:

if(file_exists(152.jpg)

and I wouldn't know how to find a file with a random number on the end.

Thanks!!!

I believe you can use a meta tag for this. Try searching the Web for "meta no-cache".

Thanks, but for some strange reason I cannot get it to even repeat the problem.

If you still need it, something like this should do the trick:

header("Cache-Control: no-cache, must-revalidate");
header("Expires: Mon, 26 Jun 1989 07:00:00 GMT");
