Actually, it seams to be:

On secure I get:
Cache-Control: public, s-maxage=600, max-age=0
There is a Firefox bug: https://bugzilla.mozilla.org/show_bug.cgi?id=345181
It's marked fixed but I'm not so sure.

On normal en.wp I get:
Cache-Control: private, s-maxage=0, max-age=0, must-revalidate

There's also no ETag or Last-Modified so even if there is a max-age that
must-revalidate could have the effect of nullifying the max-age.
