Test: Last-Modified • If-Modified-Since • Not-Modified

This page sends a "Last-Modified: Yesterday/Now" HTTP response header

Last-Modified: Mon, 24 Sep 2018 09:22:25 GMT

and should respond with 304-Not Modified if you request it (twice) with an "If-Modified-Since: Today/Now" HTTP request header:

If-Modified-Since: Tue, 25 Sep 2018 09:22:25 GMT

(Please read the tutorial, and here is a tool to test Last-Modified/If-Modified-Since/Not-Modified functionality.)
