How can I disable any type of cache?

[John Pastrovick]

I mean any kind, browser, server..., ANY.

I have a script that erases and adds thumbs and the cache is a nightmare.

There is an XP folder tool options to enable thumbs cache.

I want to disable it (and any other type) regardless of this option status.

Thanks.

add this headers
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // always
modified
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Pragma: no-cache"); // HTTP/1.0

other way to add random variable to link like this
<?
echo "<a href=name.php?id=".time().">NAME</a>";
?>

I was using this header which did not work It is only different from
your suggestion in adding the 4th line but I do not think that makes
any difference.

I have to test adding a random variable to the URL, but I have seen
that Win XP has this option to enable thumbniail cache which does not
care about random variables. It looks for image names in the cache and
in my upload application the images are actually renamed to image
names already in the cache.
From php script aa.php which has image1.jpg and image2.jpg I send an
action to bb.php and there image1 is erased and image2.jpg is renamed
to image1.jpg.
Then aa.php is reloaded on bb unload. And the problem is image1.jpg
appears as the old image1.jpg.

When I look in the image folder or exit the browser and return to load
it again, everything is correct. But in the inmediate reload after I
erase, the old image with the name image1.php is sent to the browser
from the cache.

I don't know why you execute in such way but anyway try to rename image2.jpg
in bb.php using any_random_name.jpg and pass this name to aa.php
