title: Broken caching of images loaded from homemade webserver
body: <p>A while ago I wrote a webserver which I'm using on a site of mine.</p>
  
  <p>When I navigate to another page in Chrome while the images from this homemade webserver are still loading, they stay cached as only half-loaded.</p>
  
  <p>Is this a known bug in Chrome, or an issue with my implementation of the HTTP protocol?</p>
  
  <p>My webserver uses E-Tags for caching.</p>
