How to show google.com in an iframe?

I am researching possible methods of running a proxy server for a school project.

I thought about using iframes to load a web page inside another web page, so I made a test.

Here is my HTML:

<html>
  <body>
    <IFRAME SRC="http://google.com" WIDTH=1024 HEIGHT=768>
      Not loaded
    </IFRAME>
  </body>
</html>

However, http://google.com doesn't load, and instead the iframe remains white.

On further inspection, Google Chrome's GET request to load google.com has been cancelled.

I suspect that google stop people from loading their site in iframes, but why is this, and what are the effects of it?

Edit: I forgot to mention, other websites (like my own) work fine.

  • The effects are pretty obvious: a few lines extra in their JS and nobody can load google.com in an iframe. – 11684 Sep 04 '12 at 14:11

Because it has X-Frame-Options Header policy and browsers tend to respect those policies.

Read here and here

The "X-Frame-Options" allows a secure web page from host B to declare that its content (for example a button, links, text, etc.) must not be displayed in a frame of another page (e.g. from host A). In principle this is done by a policy declared in the HTTP header and obeyed by conform browser implementations.
