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=",
"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!

Re: [flexcoders] Re: Caching problem
Hmm, i've had this experience on both Apache & IIS. I'm not talking about a
server cahce, I believe this is browser related. Upload SWF to server, and
do not see change in browser till cache is cleared. No one else experiences
this?
My current understanding is that since nothing about the page itself
changed, the browser (IE 6 & 7) is caching this resource. Am i wrong?
I've copied the original post, below.

Hi there!
I have an xml file that needs to be loaded eventually using a
URLRequest. I'm trying to avoid loading a cached file using these
headers:
urlRequest.requestHeaders.push(new URLRequestHeader("Cache-
Control", "no-cache, no-store, max-age=0, must-revalidate"));
urlRequest.requestHeaders.push(new URLRequestHeader
("Expires", "Fri, 30 Oct 1998 14:19:41 GMT"));
urlRequest.requestHeaders.push(new URLRequestHeader
("Pragma", "no-cache"));
It works ok in firefox and IE6.0.2900, but I still obtain a cached file
in IE6.0.3790+ and IE7.
Do I need to add any more headers? or what's the problem here?
Thanks in advance

Re: [flexcoders] Re: Caching problem
went away after I reset IE to check every time far a new file Ah yes, that's right. I used to do that, but it doesn't gaurantee that my users have the same settings. Hence, my dilemma!

It also made a big difference to make sure that the server was sending the correct caching headers. Check the HEAD on a request to determine if it is sending the correct expires header. I only do this for development. Production environments should be able to run without problems if there are browsers caching things. --- In flexcoders@yahoogroups.com , slangeberg <[EMAIL PROTECTED]> wrote: > > You don't experience this with IE?

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.
