title: IE is claiming not to recognize the text/javascript MIME type
body: <p>We have been developing a Ruby on Rails application. We have recently re-deployed this application behind an Apache proxy which uses HTTPS.</p>
  
  <p>Since we've done this one of our users gets sent to the following page when trying to use the app: <a href="http://shell.windows.com/fileassoc/mimeassoc.asp?mime=text/javascript" rel="nofollow">http://shell.windows.com/fileassoc/mimeassoc.asp?mime=text/javascript</a>, which says:</p>
  
  <pre><code>MIME Type: text/javascript
  Description: UnKnown
  Windows does not recognize this MIME type. 
  </code></pre>
  
  <p>Does anyone know under what circumstances IE would claim not to know what to do with a <code>text/javascript</code> file? It's just this one user so far.</p>
  
  <p>Windows 7 / IE 8 and XPsp2 / IE8</p>
  
  <p><em>EDIT</em> Adding the full HTTP response that IE barfs on</p>
