It does that (or is at least supposed to) on all requests that
is cacheable. Pragma: no-cache only says that the request can't
be server from a cache. The result may and should be cached.

It is the way it should be. If a user gets a new page by pressing
reload, then the next user should get the same page. The exeption
is when the new page is uncacheable (then the old page may
be left in the cache).
