Is there a way to make a Security Sandbox for javascripts and css behavior files for ie?

I am interested in using javascripts from one domain in a page loaded from another domain. Is there anyway to make a "security sandbox" for javascripts and css behavior files for Internet Explorer so that the scripts have full access to the DOM of the page they are loaded into?

Right know, some files don't load and others make access denied errors.

I know this exists for Adobe Flash movies that allows a parent movie to load child movies from other domains and it would be so nice to have the same possibility with javascript.

One way of doing it would be to run a script on your server which loads the code from the remote server and sends it to the browser, so your page would look like this:
<script type="text/javascript" language="javascript" src="jsproxy.php?url=http://example.com/ascript.js" />
... and jsproxy.php would be a script to load the javascript from the other site. Depending on your server, any one of hundreds of scripts will work for you. Try a google search to find one that works for you ( http://www.google.com/search?q=php+javas... )

Thanks!

That might just do the trick. I'll have to think about it.

After posting this I found out about the security policy called the "Same Origin Policy"
http://www.mozilla.org/projects/security...

So that rules out any "sandbox" ideas.

It seems like a proxy, either using your script or some Apache configuration like mod_proxy
http://httpd.apache.org/docs/1.3/mod/mod...

would be the only way to add this functionality to a site.
