title: What is the correct mime-type for serving an iPhone .ipa file?
body: <p>I'm trying to post .ipa files onto our apache web server for our beta testers to download. Currently I'm using the following line in .htaccess to serve the files:</p>
  
  <pre><code>AddType application/octet-stream .ipa
  </code></pre>
  
  <p>This works great in Safari and Firefox, but in IE the .ipa extension is removed and is instead replaced with .zip.  So instead of MyApp.ipa, IE users will get MyApp.zip.</p>
  
  <p>I know that I could just zip up all the .ipa's before putting them onto the server and then I wouldn't have to deal with any of this, but I'd like to avoid that extra step if there is a more elegant solution server-side.  </p>
  
  <p>Or rather, is it possible to simply prevent IE from altering the file extension?</p>
