Hi again :slight_smile: my action script file loads an XML file, dynamically created with PHP ,
These are the lines which load the xml object in flash.


menuXML = new XML();
        menuXML.ignoreWhite = true;
        menuXML.load("mp3a.php");

mp3a.php scans files and folders in mp3/a directori on my apache server and then creats list.

Wat can i do to cach this xml ? And is it posiible to cache it about 1 day?or12 hours? :slight_smile:
