Question

I am using the following simple iFrame code to load Yahoo but it\'s not loading anyway. in Chrome Inspector I see the URL status as 301 first and then cancel. Any idea why i

Answer 1

Its also very easy to ask site not to load if you are in an iframe with simple javascript. For example, twitter does this

<script type="text/javascript">
//<![CDATA[
    if (window.top !== window.self) {
        document.write = "";
        window.top.location = window.self.location;
        setTimeout(function () {
            document.body.innerHTML = '';
        }, 1);
        window.self.onload = function (evt) {
            document.body.innerHTML = '';
        }; 
    }
//]]>
</script>

I did not see a console error here and so I guess this is the case here.

The Yahoo! JavaScript is obfuscated but you can see they are definitely removing something at this snippet. (Code taken from yahoo website)

if(self!==self.top){b=function(){if(g.readyState=="complete"){f.remove(g,e,b);

Answer 2

actually yahoo , google and such website doesn't allow iframes to their site. They blocks iframes to show their website

Answer 3

If the site hosting the webpage forces the use of a secure HTTPS connection, some browsers (chrome for sure) will require that all network resources use HTTPS as well.

The URL in your current iframe is using HTTP src="http://yahoo.com"

Try using HTTPS: src="https://yahoo.com"

Answer 4

My latest Firefox silently refused to load an unencrypted iframe when the parent was unencrypted. It showed no console messages about an attempt to load the child or any reason to not try doing so.

Answer 5

You probably get an error message in the log that reads something like this:

"Refused to display document because display forbidden by X-Frame-Options."

To answer your question:

Yahoo is doing this to avoid clickjacking attacks, by ensuring that their content is not embedded into other sites.
