Hello all,
I am creating a a script in which a dynamic graph is generated through gd
library. The format of the picture is jpeg. Now the problem is that the
browser is caching the images and after updating also it is displaying the
older image.
Currently for clearing the cache i am using this code
<?php
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: no-cache");
header("Pragma: no-cache");
?>
But this code is not working me. Please help me.
Regards
Manoj

I had a similar problem -- if memory serves me correctly, I solved it
by appending a random string to the jpg, such as graph.jeg?id=<some
random string>. The image tag won't process the addition and the
browser treats it as a new image. I think this worked for most
browsers, but I may be wrong.
