check page loaded in an iframe

[Christian Schmitt]

I load a page into an iframe that comes from another server. If this
page is not accessible, this server redirects to a login page.
I want to check if the correct page was loaded in the iframe in order to
give the appropriate instructions if the redirect occured. My idea was
to use framename.search('some text on the page'), but I'm not allowed to
do this for a page from a different server.
Any idea how to do something like this, or is this simply impossible?

I hope you are allowed to use the content of the third party.

You need a signed script, otherwise the Same Origin Policy gets you.
Ask friend(!) Google for details.

Sure I am.

But signed scripts don't work with IE, right? I browsers of the
netscape-family, I can use the UniversalBrowserRead privilege even
without signed scripts, the user just has to confirm the warning dialog.
But what do I do in IE? Asking the user to add my page to the trusted
sites isn't really an option. At least I wouldn't do this as it gives
the site just too much power. Isn't there any equivalent to
UniversalBrowserRead in IE?
I didn't find anything in google, that's always my first stop.
