-      # Sends the file. This uses a server-appropriate method (such as X-Sendfile)
-      # via the Rack::Sendfile middleware. The header to use is set via
-      # config.action_dispatch.x_sendfile_header, and defaults to "X-Sendfile".
-      # Your server can also configure this for you by setting the X-Sendfile-Type header.
-      #
-      # Be careful to sanitize the path parameter if it is coming from a web
-      # page. <tt>send_file(params[:path])</tt> allows a malicious user to
-      # download any file on your server.
-      #
-      # Options:
-      # * <tt>:filename</tt> - suggests a filename for the browser to use.
-      #   Defaults to <tt>File.basename(path)</tt>.
-      # * <tt>:type</tt> - specifies an HTTP content type. Defaults to 'application/octet-stream'. You can specify
-      #   either a string or a symbol for a registered type register with <tt>Mime::Type.register</tt>, for example :json
-      # * <tt>:disposition</tt> - specifies whether the file will be shown inline or downloaded.
-      #   Valid values are 'inline' and 'attachment' (default).
-      # * <tt>:status</tt> - specifies the status code to send with the response. Defaults to '200 OK'.
-      # * <tt>:url_based_filename</tt> - set to +true+ if you want the browser guess the filename from
-      #   the URL, which is necessary for i18n filenames on certain browsers
-      #   (setting <tt>:filename</tt> overrides this option).
-      #
-      # The default Content-Type and Content-Disposition headers are
-      # set to download arbitrary binary files in as many browsers as
-      # possible.  IE versions 4, 5, 5.5, and 6 are all known to have
-      # a variety of quirks (especially when downloading over SSL).

-      #

-      # Show a 404 page in the browser:
-      #
-      #   send_file '/path/to/404.html', :type => 'text/html; charset=utf-8', :status => 404

-      # http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.11.
-      #
-      # Also be aware that the document may be cached by proxies and browsers.
-      # The Pragma and Cache-Control headers declare how the file may be cached
-      # by intermediaries.  They default to require clients to validate with
-      # the server before releasing cached responses.  See
-      # http://www.mnot.net/cache_docs/ for an overview of web caching and
-      # http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9
