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

Question

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

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
