Forced Reloading

Copy linkTweet thisAlerts:

grabImage = new Image();
grabImage.src=”/system/logit.php”;

I know when your looking at this you must think I’m crazy but the commands above do in fact call and run the php script. but it can only be run once in the life of the page that made the call. thats because it’s loaded into cache.

is there a way to force a reload without having to refresh the whole page, so the image/php script in the cache is overwritten and reloaded on command?

This way the script can be run a number of times.

@DaveRasauthorAug 04.2003 — I wish to thank ibidris2003 for his help. He gave me many ideas.

I was able to work out how to get around my problem by placing the following lines in my php script which stops the caching of the img allowing the 2nd php script to be run multiable times.



header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");

header("Cache-Control: no-store, no-cache, must-revalidate");

header("Cache-Control: post-check=0, pre-check=0", false);

header("Pragma: no-cache");

Success!
