In HTML5, iframe comes as a replacement for frameset.


iframe has been around since HTML 4. It was introduced at the same time as frameset. There isn't a replacement for frameset since framesets are just awful.


Is this expected?


Yes. If the server says that only pages from the same origin may frame a page, then it will appear blank if framed from a different origin. Browsers display an error message in the console.


Is there a workaround to make Google not break the "Cached" link?


Don't stick it in a frame, or cache it yourself.


Why is there a need for this header


To defend against phishing and other unsavoury attempts to pass off other people's content as one's own.

(NB: If you do cache it yourself, then be careful you aren't opening yourself up to a copyright claim).


isn't webcache.googleusercontent.com already explicitly dedicated to, well, user content?


No. It's content scraped from third party sites all over the
