title: browser-caching works except for svg-images
body: <p>I'm having trouble with the browser-caching of SVG-files. </p>
  
  <p>In my .htaccess, everything seems to be fine (at least it is rather complete) but no matter what I try, it seems as if the SVG-images aren't making their way into the browser's cache.</p>
  
  <p>there's </p>
  
  <pre><code>&lt;IfModule mod_expires.c&gt;
      ExpiresActive On
      ...
      (various other file-types)
      ...
      ExpiresByType image/svg+xml "access plus 1 month"
      ExpiresDefault "access plus 1 month"
  &lt;/IfModule&gt;
  </code></pre>
  
  <p>in the .htaccess, I tried </p>
  
  <pre><code>ExpiresByType image/svg+xml A2592000
  </code></pre>
  
  <p>too, but nothing works. I also tried to change the mime-type to text/svg+xml. no good neither.</p>
  
  <p>What could cause this failure?</p>
  
  <p>Thanks </p>
