This is such an annoying thing. And it seems as though no one is
willing to cover it in any manual, book or tutorial. Apparently the
problem is that PHP sessions automatically set the no-cache header. So
at the top of each script, after the session_start() function set
header("Cache-Control: public"); That will the trick. Actually it may
work too well but at least your visitors won't get discouraged by that
annoying message.
