There is a way to make sure your force new file all the time rather than cached one.
You need to add some random junk to the file, this will make the server download new
copy each time the browser seek the file as it won't be identical to the one found in
cache while comparing.
It apply to loading swf or variables:
else you can always stamp the file with "time" so each file will never be
identical to another forcing browser to get new each session.
FILE.swf?" + new Date().getTime()
For example :
<PARAM NAME=movie VALUE="FILE.swf?" + new Date().getTime()">
Same apply if you load content into flash, to both, variables or swf files
