I need the inline script to be in the iframe content so that the test does
not execute until the iframe has started loading (but has not completed). I
tried the php below, but the script doesn't execute until after the sleep. I
don't know php. Is my php wrong? Or does DRT buffer the response until the
entire response is complete?
header("Expires: Thu, 01 Dec 2003 16:00:00 GMT");
header("Cache-Control: no-cache, no-store, must-revalidate");
header("Content-Type: text/html; charset=utf-8");
