How to serve this file with these HTTP headers?
<p>I am using a shared hosting, so I can't edit Apache settings.
I need to allow users to download a .crx file in this way:</p>

<pre><code>1) The file has the content type application/x-chrome-extension
2) The file is not served with the HTTP header X-Content-Type-Options: nosniff
3) The file is served with one of the following content types:
- empty string
- "text/plain"
- "application/octet-stream"
- "unknown/unknown"
- "application/unknown"
</code></pre>

<p>How can I do this in PHP or in others way ?</p>
