IE7 caching swf

Recently I have been experiencing some caching issues with IE7 and my swfs. If I upload a new swf to my server, the browser doesn’t pick it up. To fix the problem I have to delete all my temporary internet files and then refresh. Someone suggest Ctrl F5, but that doesn’t do anything to help the situation. As I say this has only been recently like since the first of January.

Anyone else experiencing this problem?
