I'm having a bit of an awkward time with Media Views recently after
extending my site to use a controller I had built using it (Document
Controller). I'm experiencing a couple things:
1. Internet Explorer seems to not actually load the file if caching is
either set to false, or simply not set.
2. It seems that randomly (I have yet to pinpoint and replicate this)
the Auth session will require re-authentication for the media file
that is being downloaded (not a forced download), even if a user just
logged in. Once they re-authenticate for any Media View file, any
further media views seem to open just fine.
My controller's function to use the Media Views is below:
function download($path, $filename){
$this->view = 'Media';
$extension = $this->getExtension($this->here);
$params = array(
'id' => $filename.'.'.$extension,
'cache' => 10, //10 seconds -- had issues with
no cache
'download' => false, //render in browser if possible
'extension' => $extension,
'path' => DS.'documents'.DS.$path.DS
);
$this->set($params);
}
Prior to these issues, I had the cache set to 15 minutes. I tried to
change it to use no cache as users would look at an old file,
overwrite that file, and then check the new file to see if it was
successful - because of the cache set in the browser, they wouldn't
see the new file. I'm not as concerned over fixing that problem as I
am with the two problems listed above.
Does anyone have any ideas?
I'm somewhat concerned with the following lines in cake/libs/view/
media.php @ line 186:
if(!is_numeric($cache)){
$cache = strtotime($cache) - time();
}
If $cache is true, or even false, the cache will end up being
negative. Was this intended? Could this cause issues with IE? I'm
still unsure where the re-authentication issues could be occurring.
(I'm running CakePHP 1.2.4.8284 according to cake/VERSION.txt - but
the source code from the example came from the Cake API -
http://api.cakephp.org/view_source/media-view/#l-186)
