X-Frame-Options Compatibility Test

This web page tests your browser's x-frame-options support. The X-frame-options header decides whether if another web page can put a given page (with the header) in an iframe. This is commonly used as a defense against clickjacking.
Deny: Expected: 1 green check (or empty)
SameOrigin: Expected: 2 green checks (or 1 green check and one empty)
Allow-from: Expected: 2 green checks (or 1 green check and one empty)
