I converted a plain vanilla HTML page to HMTL5/CSS3 with a responsive layout, and for security reasons (dictated by the security people) the page must never cache.

The page previously used `<meta http-equiv="Pragma" content="no-cache">` and `<meta http-equiv="Expires" content="-1">` to prevent the page from being cached.

What replaces this in HTML5? 
How do you prevent an html page from caching in the client? 

I've spent a week reading about manifest files, but they seem to do exactly opposite of what I want as attaching a manifest file explicitly causes the page it is attached to to cache. 

And please don't refer me back to the w3c definition of which meta elements are now allowed — I understand that HTML5 does not include the `cache-control` or `Pragma` in `meta` elements. 

I need to know what it does include that will prevent a page from being cached.
