title: WebDAV Specification thumbnail/preview file image
body: <p>Now I'm using WebDAV protocol for sharing files for writing my own webdav client.</p>
  
  <p>I want to implement fetching thumbnails previews from specified file located web server (nginx/Apache/other).
  WebServer must generate thumbnail/preview image and return that with PROPFIND request or another way.</p>
  
  <p>Is there any property from propfind or response header described in RFC and supported from webservers with nginx/Apache?</p>
