  # Manifest files

    # If you are providing a web application manifest file (see the
    # specification: http://w3c.github.io/manifest/), it is recommended
    # that you serve it with the `application/manifest+json` media type.
    #
    # Because the web application manifest file doesn't have its own
    # unique file extension, you can set its media type either by matching:
    #
    # 1) the exact location of the file (this can be done using a directive
    #    such as `<Location>`, but it will NOT work in the `.htaccess` file,
    #    so you will have to do it in the main server configuration file or
    #    inside of a `<VirtualHost>` container)

    #    e.g.:

    #       </Location>
    #
    # 2) the filename (this can be problematic as you will need to ensure
    #    that you don't have any other file with the same name as the one
    #    you gave to your web application manifest file)
    #
    #    e.g.:
    #
    #       <Files "manifest.json">
    #           AddType application/manifest+json               json

# ------------------------------------------------------------------------------

# (1) Try to re-enable the Cross-Site Scripting (XSS) filter built into the
#     most recent web browsers.
#
#     The filter is usually enabled by default, but in some cases it may be
#     disabled by the user. However, in Internet Explorer for example, it can
#     be re-enabled just by sending the `X-XSS-Protection` header with the
#     value of `1`.
#
# (2) Prevent web browsers from rendering the web page if a potential reflected
#     (a.k.a non-persistent) XSS attack is detected by the filter.
#
#     By default, if the filter is enabled and browsers detect a reflected
#     XSS attack, they will attempt to block the attack by making the smallest
#     possible modifications to the returned web page.
#
#     Unfortunately, in some browsers (e.g.: Internet Explorer), this default
#     behavior may allow the XSS filter to be exploited, thereby, it's better
#     to tell browsers to prevent the rendering of the page altogether, instead
#     of attempting to modify it.
#
#     http://hackademix.net/2009/11/21/ies-xss-filter-creates-xss-vulnerabilities
#
# IMPORTANT: Do not rely on the XSS filter to prevent XSS attacks! Ensure that
# you are taking all possible measures to prevent XSS attacks, the most obvious
# being: validating and sanitizing your site's inputs.
