Cache problem

[jpistone]

Is there a way to overwrite a client's cache file? Suppose I have a file called "recent.pdf" and replace it daily., but keep the same name. When someone goes to the site, the browser calls up the cached version (yesterday's) instead of the newer one. Short of redesigning things, is there a quick fix to overwrite the file from the same originating site with the same name? Would a cookie do it? Thanks.

add this header to the script
[code]header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past[/code]
