html - How to show google.com in an iframe?

Question

I am trying to put google.com into an iframe on my website, this works with many other websites including yahoo. But it does not work with google as it just shows a blank iframe. Why does it not render? Are there any tricks to do that?

I have tried it in an usual way to show a website in an iframe like this:

<iframe name="I1" id="if1" width="100%" 
 height="254" style="visibility:visible" 
 src="http://www.google.com"></iframe>

The google.com page does not render in the iframe, it's just blank. What is going on?

Answer 1

The reason for this is, that Google is sending an "X-Frame-Options: SAMEORIGIN" response header. This option prevents the browser from displaying iFrames that are not hosted on the same domain as the parent page.
