[flexcoders] Re: SWF Cache
If you can add content (besides your Flex app) to the server, you can do both. http://www.adobe.com/devnet/flex/articles/version_sync_ria.html It's an older article but the concepts still apply. Long story short, your Flex app can periodically read some server side data (say, an XML page via HTTPService), compare the version number of the app to the latest available version, and force the browser to reload if a newer version is available. --- In flexcoders@yahoogroups.com, Don Kerr [EMAIL PROTECTED] wrote: Thanks Kevin!

Thanks Doug. It is brilliantly simple ... and I like using a CFC to handle it. I'll give this a try. Thanks!

Hey Don- It's a quick and dirty trick to prevent caching, but if you're just writing a single Flex app (1 swf, no modules) then you can append some random GET data to the tail end of the swf extension.
