Security violation foreign domain?

Hello,

I have been using Javascript to access some audio files from another
server and there has been no associated problem with IE or FF but
Opera gave an error message which led me to read that accessing files
from a "foreign" domain name is a security violation for Javascript.

This true? If yes, why do all above browsers allow it to happen?!

The reason for putting the audio files on another server was to cope
with a possible heavy demand brought about by a radio mention of this
site.

Any workaround?

Any thoughts?

Cheers

Geoff

Those questions can only be answered if you explain how your code
works. Javascript/browsers don't usually have built-in "access some
audio files" methods.
Probably, yeah.
Use flash instead? (I'm only half kidding).

Joost,

I am using soundmanager2

http://www.schillmania.com/content/p...soundmanager2/

the audio files are accessed using an http link such as

soundManager.createSound({
id:'mySound'+t,
url:'http://www.differentsite.com/audio/Track' + (+t+35) + '.mp3',
onfinish:function(){document.getElementById('test' +t+1).className =
'visibleDiv2'} });
soundManager.play('mySound'+t);
count++;
}

Cheers

img that points to some resource on another server. That is totally
legit and shouldn't really raise any concerns. I'm surprised that
Opera does.

If accessing files from another domain was restricted, there wouldn't
be much use for the internet really :).

The problem comes into play when you try to make an XMLHttpRequest to
another domain or access the DOM of a page provided from another
domain. That does not appear to be the issue here. So I wouldn't be
concerned.

underlaying code. From a quick look soundmanager2 simply creates
OBJECTs for Flash movies and later trying to interact with them using
Javascript on the page. ActionScript (ECMAScript implementation used
in Flash) has its own security model that doesn't coerce with the
browser security model in many details. This way the
ActionScript<>Javascript interaction is normally disabled or limited
on current browsers so to keep both models by their own.

VK,

I'm not sure that I totally follow you - is taking the mp3 files from
the other server a problem or not?!

IE and FF do not complain (ie no error messages) and play the files.
Opera complains but plays them...

I am concerned that other users of IE and FF may have a different
experience from mine and might not be able to play the sounds?!
