It is possible for a iframe to redirect the page it is on?
Example:
You go to www.fuu.com
On fuu.com there is a iframe
In that iframe is a website the redirects to another website.
Is it possible for fuu.com to be redirected? instead on just the iframe going to another page?

No. An iframe is treated as a separate document with its own DOM. A redirect within the iframe is treated as a redirect only within that iframe.
In other words, The main page can not be redirected by an iframe.
EDIT: I was wrong. Consider the following situation
Top Page
<html>
<body>
<iframe src="redirect.html"></iframe>
</body>
</html>
redirect.html
<html>
<head>
<script>
window.top.location = "http://www.w3schools.com";
</script>
</head>
</html>
That does redirect the top page to w3schools.com
To prevent this type of thing, you can remove that by using the following
<html>
<body>
<iframe src="redirect.html" sandbox="allow-scripts"></iframe>
</body>
</html>
In chrome, this would give you the following error:
Unsafe JavaScript attempt to initiate navigation for frame with URL 'http://127.0.0.1/scg/?search=&submit=Search' from frame with URL 'http://127.0.0.1/scg/iframeRedirect.html'. The frame attempting navigation of the top-level window is sandboxed, but the 'allow-top-navigation' flag is not set.
The allow-scripts allows Javascript to still be executed in the iframe but removes window.top from allowing to execute. Check this out
