 Replying to [comment:2 johnbillion]:
 > If you log out, or if you view your site in an incognito browser window
 or from another device, those headers won't be present and caching will
 work as expected.

 Well, @wuxu did mention in [comment:1 the first comment] that caching is
 not working even for non-logged-in users.  However, the date is different:
 "Thu, 19 Nov 1981 08:52:00 GMT".  That date is not used by WordPress, but
 it is used by PHP when calling `session_start()`.  Since core WordPress
 does not call `session_start()`, I would guess that there is a plugin (or
 theme) installed which is calling `session_start()`.
