Flex Google Chrome cache issue

I have one issue with my web project we use to release a new swf, the older version gets cached in Chrome and you have to clear your cache to see it. The same does not happen in Firefox and IE.

Environment Used: - Web Application (Flex), Browser tested on IE, Firefox and Google Chrome.

Is there any programmatic solution which can help to solve this problem by using JavaScript, HTML or through Flex?

Solution tried (Does not work): -

I have the following headers:

meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

meta http-equiv="cache-control" content="no-store, no-cache, must-revalidate" />

meta http-equiv="Pragma" content="no-store, no-cache" />

meta http-equiv="Expires" content="0, -1" />

Use a naming convention for your swf that includes the version and build number. The file name difference will address caching as well as being a best practice for numerous reasons.

It's hard to argue that it's better to just guess which version of the code base "myApp.swf" is versus "myApp.2.1.0015.swf" and knowing immediately.

Here is a good version nomenclature.

I'm always confused why people are so adverse to a rename operation after compiling. Make it part of your deployment routine. Updating a little HTML to point the the appropriate build is not that time consuming.

I promise users won't care if you're builds are actually appropriately named, in fact, I doubt they'll notice other than not having any more caching issues.

If you're re-distributing you're app and patches so much and so often that it is too much hassle for 2 minutes of html to point to the new build, you're doing it wrong.
