title: How to set MIME type of application/vnd.apple.pkpass in order to share pass by link or email
body: <p>I just created an app and a pass, so I can add the pass to the PassBook in iPod, but I cannot share the pass by email or link from web server. From the documentation I read from Apple, I need to add a MIME type as <code>application/vnd.apple.pkpass</code>. However, I don't understand clearly what steps should I do. I don't know how to use MIME type.</p>
  
  <p>How should I add this MIME type in order to use pass from my web service?</p>
