title: Cache Include Files While Developing PHP Script
body: <p>In the past few days, when I edit a PHP script that is included in another script, the browser is using a cached version and I'm not seeing my changes.</p>
  <p>I have tried with no success:</p>
  <ul>
  <li>in Chrome developer tools, &quot;disable cache&quot; on Network tab</li>
  <li>in Chrome developer tools, ctrl-click on refresh and select &quot;empty cache and hard reload&quot;</li>
  <li>adding PHP header() calls with no-store, no-cache, etc.</li>
  <li>shift-refresh in Chrome</li>
  <li>using Safari</li>
  <li>restarted my Docker Ubuntu/Apache sandbox that is &quot;https://localhost&quot;</li>
  <li>passing a unique argument on the URL, e.g. ?junk=1234</li>
  <li>a Chrome extension to clear the cache</li>
  </ul>
  <p>I've developed for years without experiencing this problem, and suddenly I can no longer see my changes.</p>
  <p>I can't figure out what changed to break it.</p>
  <p>Any ideas?</p>
