title: zip mime types, when to pick which one
body: <p>So far for Mime Types for Zip files I've seen:</p>
  
  <ul>
  <li>application/octet-stream</li>
  <li>multipart/x-zip</li>
  <li>application/zip</li>
  <li>application/zip-compressed</li>
  <li>application/x-zip-compressed</li>
  </ul>
  
  <p>I guess my question is which is the "best" and why? Why is there so many choices? I use winrar and it doesn't seem to care what the Mimetype is, but WinZip seems to only like multipart/x-zip and application/octet-stream. is there a Mimetype I can have all Zip files be downloaded as that will work in all programs?</p>
  
  <p>thanks!</p>
