title: Is it possible to get an original mappath of an attachment on ASP.NET?
body: <p>Supposing I'm doing something like this:</p>
  
  <pre><code>Response.ContentType = "image/jpeg";
  Response.AppendHeader("Content-Disposition", "attachment; filename=test.jpg");
  Response.TransmitFile(Server.MapPath("~/images/original.jpg"));
  Response.End();
  </code></pre>
  
  <p>Can any user or hacker get the "original.jpg" place of the file?</p>
  
  <p>If yes, how?</p>
