pragma was the way to do this in http 1.0; http 1.1 (which most web
servers will use by now, i suppose) says its implementation is optional
and suggests using Cache-Control: no-cache.

anyhow, i think it should be up to the server to decide what to cache,
so the server should tell what must not be cached by issuing a
must-revalidate. always overriding cache seems to be bad practice; if
this is necessary in some cases (which often result from badly
configured servers), there should be an option to override cache
(disabled by default).
