Hi,

I found that page created by "Generate excel friendly report" link cached by browser.

Once generated excel report appear unchanged after html report was changed.

So, I suppose this code for csv.php

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("Pragma: no-cache");

header("Content-Type: application/vnd.ms-excel");

header("Content-Disposition: attachment; filename=".uniqid('').'.xls');

header("Expires: 0");

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