Now that I think about it... yes; but I send the last modified header anyway
the first time (when $_SERVER['HTTP_IF_MODIFIED_SINCE'] == null):
header('Last-Modified: '.gmdate('D, d M Y H:i:s',$last_modified).' GMT');
So if it isn't exactly equal, then the browser cache simply doesn't have the
latest version. It is impossible anyway that the browser can have a newer
version that doesn't previously exist on the server.
My best guess is that it doesn't affect the process: when I implement that
code in my class, it enters that part (meaning all the comparisons are ok)
but afterwards it keeps sending an "200 OK" header when I explicitly tell
Apache to send the "304 Not Modified" one.
Greetings and thanks for sharing :)
