title: Does my apache cache my images?
body: <p>I have a folder for customer avatar upload and I set up an apache server pointing to this folder to get customer avatar images.
  It seem to be a very strange symptom my system get right now as following:</p>
  
  <ol>
  <li>I update an avatar image in the folder</li>
  <li>I access to the image by browser, but I see it displays the old one on browser though I refresh (Ctrl+F5) many times.</li>
  <li>After a time duration (nearly 1 min), I refresh the above url, and I got the lastest image dislayed.</li>
  </ol>
  
  <p>Is this symptom relating to my Apache configuration? Could anyone help me to figure out which setting affects? Thank you!</p>
