Overview
Some web applications will serve untrusted HTML for download. By default, some versions of Internet Explorer will allow you to open those HTML files in the context of your site, which means that an untrusted HTML page could start doing bad things in the context of your pages. For more, see [this MSDN blog post](http://blogs.msdn.com/b/ie/archive/2008/07/02/ie8-security-part-v-comprehensive-protection.aspx).
This handler sets the X-Download-Options header to noopen to prevent IE
users from executing downloads in your site's context.
Example usage:
server = HTTP::Server.new("0.0.0.0", 8080, [
Helmet::InternetExplorerNoOpenHandler.new,
# ...
])
