Or can't you build a Proxy controller for such files and let the controller
add header tags for browsers not to cache (must-revalidate, etc.)? So then
from your view instead of placing the OBJECT tag to directly find the swf
you use the controller as a source, something like
/animations/animation.swf
And then the animations controller is something like:
class AnimationsController extends AppController
{
var $name = 'Animations';
var $uses = null;
var $animationPath = WWW_ROOT . DS . 'animations';
function index($file)
{
$filePath = $this->downloadPath . DS . $file;
// Check against path injection
if (preg_match('/^[A-Za-z0-9_\-\.]*$/', $file) &&
is_readable($filePath))
{
if (!headers_sent())
{
$size = @filesize($filePath);
if ($size > 0)
{
header('Content-length: ' . $size);
}
// Disable caching
header('Cache-Control: no-cache, no-store,
max-age=0, must-revalidate');
header('Expires: Mon, 26 Jul 1997 05:00:00
GMT');
header('Pragma: no-cache');
// Set content type
header('Content-Type:
application/x-shockwave-flash');
}
readfile($filePath);
exit;
}
return $this->redirect('/');
}
}

Asunto: Re: force swf refresh
no problem,
I know the issue because I've worked with swf charts and IE keeps
caching the file.
there's something you can do, instead of putting an hash to swf, try
putting something like this in source url:
/controller/action/param?uniqueid='.uniqid(rand(),true)
