I’ve searched everywhere for a way to prevent the caching of my swf files. The last thing I tried using is the ‘Expires’ header and the Pragma no-cache header suggested by Adobe ([http://kb.adobe.com/selfservice/viewContent.do?externalId=tn\_14743](http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14743)). It sounded like a good solution but it still didn’t work for me. Has anyone found a reliable way of doing this? Can this be done using ActionScript?

I’m running Flash 8 and exporting to Flash Player 6. The browsers I’m testing in are IE 6, 7, and Firefox. Thanks in advance!
