title: NGINX - Can't set content-type header
body: <p>I'm using <code>nginx/1.10-3</code> on Debian.</p>
  
  <p>I have a file named logo.img which infact is an svg.</p>
  
  <p>I've modified <code>/etc/nginx/mime.types</code> to include the <code>.img</code> as an extension for the svg file type: <code>image/svg+xml   svg svgz img;</code></p>
  
  <p>But the headers of the file served is still <code>application/octet-stream</code></p>
  
  <p>For some bizarre reason, i've been asked to serve the <code>.img</code> file as an svg for a logo on a site, i've got it to work on Apache2 using mime magic. But, as far as i know, that doesn't exist on NGINX.</p>
