title: Cancel a file upload using .Net client for Amazon S3
body: <p>I'm writing an app that allows users to browse and upload large files to Amazon S3 via a web application.  I'm using the Amazon AWS library for .Net.  However because the files are large I want to provide a 'Cancel' option on the website.  I can't see anything in the API as to how to cancel a file that's uploading using S3.  Does anyone know how to cancel file uploads?</p>
  
  <p>Thanks.</p>
