HTML5-compliant cache-control no-cache inside the document?

This is probably a duplicate question but none of the solutions I've found by searching the internet will validate at w3c.开发者_开发问答

I don't have granular control at the document-level on the hosting-company's server, so I need to include the no-cache directive in the document itself. Are cache directives inside the document permitted in HTML5? If so, how is it done so it validates?

Thanks

I could find no evidence that html5 still supports this functionality. More info is here: http://www.w3schools.com/tags/tag_meta.asp
