Solution 1:

Use the following syntax it will work.

Give the style="position:relative;" to your iframe it will work in IE.

Solution 2:

I would start by reading this Another Cross Domain iFrame Communication Technique and then look at a more elegant AJAX solution. I have seen a lot of situations where cross-domain iframes just don't work (and for good reason).

IFrames are one step above IE in the Axis of Evil (IMO)

Solution 3:

As a workaround, if all else fails, you can download the contents of something.html using server-side logic, like ASP.NET or PHP, and save it on your local web-server somewhere. Then you can avoid the same-origin policy, or you can even modify the HTML/CSS yourself on the server, for ex., remove the offending position:relative.
