Re: [Flashcoders] Re: [flexcoders] Re: Caching problem
A note on this that I don't think was mentioned in the other posts is if you have the newer AC_FL_RunContent function in your base HTML, instead of having something like this: main.swf?12345 You will have this (note the lack of any file extension): src,main?12345 So if your goal is to roll out a new version of a Flex app you could write something like the following as the first arguments to the AC_FL_RunContent function src,main?version=#variables.versionNumber#, This URL has more info: http://www.adobe.com/devnet/activecontent/articles/devletter.html The typical meta tags and no-cache headers don't see to work for these SWF files with the combination of MSIE 7, IIS 6 and the AC_FL_RunContent function. My guess is that it has something to do with the object tag being written using JavaScript instead of being present when the page is first delivered. The addition of a unique URL variable does the trick though. Enjoy, Mike Chabot On Fri, Mar 23, 2007 at 11:18 AM, slangeberg [EMAIL PROTECTED] wrote: Much better approach! Now, my question is, what do people do to prevent caching of swf files themselves? Here's the setup: I'm deploying a business app, and want all users to see the update to the SWF. However, I don't want to tell everyone to clear their cache. Should I just pass a version number to the swf request, to update to that point, ie - point to: $vers = 1.0.2; $path = /flash/myMovie.swf?vers= . $vers; object file=$path...etc. Is there a best practice for this kind of thing? I'm also curious how this will apply to Module development in Flex. How do I make sure that people have current modules, without blasting their cache, every time? Thanks, -Scott

Re: [flexcoders] Re: Caching problem
That'll work with any cache-busting you need to do. I use it in testing, to un-cache the swf file itself, when viewed on server. Ie: send rand var in url and if it's present, pass it in to swf call (swfobject + php, here): var so = new SWFObject( ProductBuilder.swf?rand=?=$rand?, product_builder, 100%, 100%, 9, #FF); Saves me the 'pain' of going through some menu to clear browser's cache, not to mention losing your browser's cache, in order to update one element! -Scott On 14 Mar 2007 08:44:42 -0700, Alex [EMAIL PROTECTED] wrote: Wow!
