This is an HTTP issue, not an HTML one, as it applies equally to
resources in other media types.

Unfortunately this really has to be considered a browser issue, and
in this context, chosing the browser to get the desired behaviour is
not an option, although there are other sorts of site where people
might well do that to gain this feature.

A paranoid partner might well install spyware, e.g. at the simplest,
run a local logging proxy.  It would take an exceptional level of 
technical knowledge to completely obscure tracks under such circumstances.
People might well be better off handling a quantifiable risk of

The precedent for this would be to use META elements.  Note I think
you meant NOHISTORY *element* after the HTML opening *tag*.  If you
had a specific element, the correct place would be with the other
metadata elements, anywhere within the HEAD element.  One could argue,
though that metadata is really attributes, rather than elements.

Public terminals should really behave as shared caches, and sensitive
pages that are not obviously private (authenticated) should use
cache-control: private.  If you want to be more aggressive in this
respect, you should use cache-control: nostore.  All this can be
done with existing, HTTP, standards.  A shared terminal really should
*always* flush history information, even if it doesn't flush its
cache of shared pages.  Internet cafes using standard products may
fail in these respects.
