title: Servlet 3.1 - Multipart async processing
body: <p>I am testing Servlet 3.1 API to process multipart requests. I am interested in processing some of the parts synchronously (text fields) and other asyncronously (file fields). At first sight it seems that it is not available in Servlet 3.1 (either totally async through request.getInputStream() in an async context or multipart processing similar to apache-commons-fileupload library).</p>
  
  <p>Is there a way to get this sync/async processing using Servlet 3.1?</p>
  
  <p>Thanks in advance for your time! :)</p>
