title: Which MIME type is correct for the .exe file?
body: <p>I try to find which MIME type corresponds to the each extension and I get ambiguous results.</p>
  
  <p>According to <a href="http://webdesign.about.com/od/multimedia/a/mime-types-by-file-extension.htm" rel="noreferrer">webdesign.about.com</a> the correct MIME for <code>exe</code> is: <code>application/octet-stream</code></p>
  
  <p>According to <a href="http://www.freeformatter.com/mime-types-list.html" rel="noreferrer">freeformatter.com</a> the correct MIME for <code>exe</code> is: <code>application/x-msdownload</code> and it says that <code>application/octet-stream</code> is MIME for <code>bin</code> extension.</p>
  
  <p>According to <a href="http://www.iana.org/assignments/media-types/media-types.xhtml" rel="noreferrer">iana.org</a> the correct MIME for <code>exe</code> (or something called vnd.microsoft.portable-executable as I don't see exe there) is: <code>application/vnd.microsoft.portable-executable</code> </p>
  
  <p>Which website is the most accurate because I don't know what kind of content type value I should expect on the server site in the HTTP header.</p>
