Stop Frame Breakout

How can I stop a frame breakout?

Programatically, do you have a way of stopping a Frame Breakout?

I have a site like digg.com and am using frames to show the topics. some sites break the frames, and remove the history of the browser, which I want to stop.

this this:

But as I see it is not (?) possible...
Another idea, you could load the digg site into a variable (php) , remove the frame breaking code and echo the modified site.
