      Description

      Currently there is not possiblity for a browser sending If-Modified-Since requests based on the expires / cache-control headers to receive a 304 Not Modified response from the server, so we must wait for this data transfer even if the intention was just to validate cache.

      This patch allows Moodle to return a 304 response when the If-Modified-Since check passes.

      This reduces traffic for e.g pages with many uploaded images (pluginfile.php) displayed.
