XML Refresh - Tried everything

1

ok, so i searched on Google and searched on Kirupa and every answer I found, I tried…but no luck…so please help:

i have a flash calendar that loads its data from an XML file which is generated through PHP. The XML file is generated just fine and everything works (because I tried in FireFox and no problems)…BUT

in IE (I’m using 7, havent tried 5, 6, or 8 yet), once the calendar is loaded, if any changes are made to the database, which PHP uses to generate the XML, they arent displayed on refresh.

Things I’ve already tried:

  1. all the header methods

<META HTTP-EQUIV="Expires" CONTENT="Tue, 01 Jan 1980 1:00:00 GMT">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">

  1. Adding a random timestamp variable to the php file that is called which displays the calendar to fool the browser into thinking its in GET mode and pulling the file from the DB again.
    ie. calendar.php?nocache=1204171390

  2. in the Actionscript in the Flash


calendar_xml = new XML();
calendar_xml.ignoreWhite=true;
calendar_xml.load("calendarxml.php")
calendar_xml.onLoad = xml_handler;

Any other thoughts? Advice?

PS - I HATE IE!
