can't prevent a flash file from being cached

#1 (**permalink**) 11-17-2009

I've spent the whole day trying to get IE8 to reload a page to display
dynamic content in a flash slide-show. nothing I've tried prevents the page
from being refreshed from the cache. all the other browsers I've tried are
working properly (firefox, chrome, opera and safari).

here are some of the things I've tried

in the page <head>
<meta http-equiv="cache-control" content="no-cache"/>
<meta http-equiv="Expires" content="Thu, 01 Jan 2009 08:00:00 GMT" />

in my .htaccess file (for my local apache server)
<Files ~ "\.swf$">
Header append Cache-Control "no-cache, no-store, max-age=1, must-revalidate"
</Files>

I've tried appending a random number to a link (not too sure this one is
even syntatically correct)
<param name="movie" value="./images/flash/vfpg.swf?rand=12" />

none of these (or anything else I've tried) make any difference. ie8 always
loads the swf from cache. of course, if I delete the cache and then reload
the page, the changes are picked up. not really a practical solution.

any other suggestions would be greatly appreciated.

this is the actual html I'm using to display the file

<object classid="clsid

27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0" width="700" height="450">
<param name="movie" value="./images/flash/vfpg.swf" />
<param name="quality" value="high" />
<param name="wmode" value="transparent" />
<embed src="./images/flash/vfpg.swf" quality="high"
pluginspage="http://www.macromedia.com/go/getflashplayer"
type="application/x-shockwave-flash" width="700" height="450"
wmode="transparent"></embed>
</object>

thanks

Hi,

A Guess?

You have the Flash ActiveX control disabled in the IE Addons Manager or you
are running in no-Addons mode?

You are in a IE Security Zone that does not allow ActiveX?

Your flash privacy settings? (IE is treating your flash cookies
differently?)

Regards.

This will only affect the HTML container, not the embedded swf files.

Have you verified with a HTTP sniffer (eg. Fiddler2) that the header is
being added to the response for the swf files?

Did you also change the src value in the embed tag? If IE8 is ignoring the
object and instead using the embed section then changing only the above will
have no effect on IE8's handling.

I think the random number in the URL to the file is the way to go, but as I
pointed out above if you didn't change the src value in the embed tag that's
most likely why it didn't work.
