title: ASP.NET MVC - how to return a FileResult, while file is at another site?
body: <p>I am writing url redirector. Now I am struggling with this:</p>
  
  <p>Let's say I have this method:</p>
  
  <pre><code>public FileResult ImageRedirect(string url)
  </code></pre>
  
  <p>and I pass this string as an input: <code>http://someurl.com/somedirectory/someimage.someExtension</code>.</p>
  
  <p>Now, I want my method to download that image from <code>someurl</code>, and return it as a <code>File()</code>. How can I do this? </p>
