Preventing The Browser From Returning A Cached SWF

A quick little snippet using Coldfusion to avoid swf caching at the browser. Swf caching can be a real pain in the but during the development and it can also be annoying in production. When you make updates, you actually want to view them. Anyway, enough chit chat:

swfobject.embedSWF('myFlashApplication.swf?nocache=#CreateUUID()#', 'myDiv', '600', '480', '9.0.0', 'expressInstall.swf',{},{});

So the above snippet, using swfobject because it does the trick so nicely, shows that we are throwing a url parameter at the swf to be injects. Essentially, this does nothing at all. However, the Coldfusion CreateUUID() function will give us an easy-to-generate unique number every time and the unique param. The browser sees a unique url and will grab the swf anew each time.
