title: How to disable cache of Apache?
body: <p>I put only index.html in /var/www/html.
  The page doesn't update after I changed the contents of index.html and reload.</p>
  
  <p>I already disable cache_module in httpd.conf like this below.</p>
  
  <pre><code># LoadModule cache_module modules/mod_cache.so
  # LoadModule disk_cache_module modules/mod_disk_cache.so
  </code></pre>
