title: Volley ImageLoader gives 403 response for some https url
body: <p>I am using <a href="https://developer.android.com/training/volley/index.html" rel="nofollow">Volley Library</a> in my project.</p>
  
  <p>I am using <code>ImageLoader</code> to load &amp; display image from <code>https</code> url.</p>
  
  <p>for example:</p>
  
  <pre><code>ImageLoader mImageLoader;
  ImageView mImageView;
  // The URL for the image that is being loaded.
  private static final String IMAGE_URL =
      "https://developer.android.com/images/training/system-ui.png";
  ...
  mImageView = (ImageView) findViewById(R.id.regularImageView);
  
  // Get the ImageLoader through your singleton class.
  mImageLoader = MySingleton.getInstance(this).getImageLoader();
  mImageLoader.get(IMAGE_URL, ImageLoader.getImageListener(mImageView,
           R.drawable.def_image, R.drawable.err_image));
  </code></pre>
  
  <p>It loads some images successfully but not all.</p>
  
  <p>For some images I got below error response:</p>
  
  <pre><code>BasicNetwork.performRequest: Unexpected response code 403 for https://developer.android.com/images/training/system-ui.png
  </code></pre>
  
  <p>Any solution to resolve this issue ?</p>
