Preventing Flex application caching in browser (multiple modules)

Question

I have a Flex application with multiple modules.

When I redeploy the application I was finding that modules (which are deployed as separate swf files) were being cached

Answer 1

What I have done is checksum the SWF file and then add that to its url. Stays the same until the file is rebuilt/redeployed. Handled automagically by a few lines of server-side PHP script
