Analyzing you site's pages to see what third party content loaded

Is there a way to "look" at your page after it loads?

[otem]

I have a page that loads an iframe with content from a third party domain.

If there is content the page loads fine, else a color of my choice will appear. In either situation the iframe's src is the same.

In the event there is no content, is there any way I might be able to use javascript to tell?

I would imagine I'm pretty much out of luck here, since the src is the same, and that it loads content from another website's domain where I don't have any privilege to.

Though, I'm hoping there might be something I might be able to try.

Maybe it would be possible to have a script "look" at the page to detect that color? Might this be possible?

Anything else I might try?

im not sure, but php would work. stripos or strpos would try to find some specific content on the page.

You are right otem, you can't access any IFRAME's content if it's from another domain.
