title: Cache control header not working
body: <p>I have set Cache control in my response header as <code>Cache-Control:public, max-age=86400</code>. But when I try to refresh page or open a new tab, it always hits my server. The response status I got is 200, server log is appeared for this request also I checked <code>chrome://cache/</code> this request is not in the list. I already looked some similar SO questions <a href="https://stackoverflow.com/questions/41424776/cache-control-not-working-without-etag">cache-control not working without etag</a> and <a href="https://stackoverflow.com/questions/12926977/why-cache-controlmax-age-dont-work">why cache-control:max-age don&#39;t work?</a>. But still with no luck. Tested on chrome 56. </p>
