# # SECURITY #
# ##############################################################################
# ------------------------------------------------------------------------------
# | Clickjacking |
# ------------------------------------------------------------------------------
# Protect web site against clickjacking.
# The example below sends the `X-Frame-Options` response header with the value
# `DENY`, informing browsers not to display the web page content in any frame.
# This might not be the best setting for everyone. You should read about the
# other two possible values for `X-Frame-Options`: `SAMEORIGIN` and `ALLOW-FROM`
# http://tools.ietf.org/html/rfc7034#section-2.1.
# Keep in mind that while you could send the `X-Frame-Options` header for all
# of your site’s pages, this has the potential downside that it forbids even
# non-malicious framing of your content (e.g.: when users visit your site using
# a Google Image Search results page).
# Nonetheless, you should ensure that you send the `X-Frame-Options` header for
# all pages that allow a user to make a state changing operation (e.g: pages
# that contain one-click purchase links, checkout or bank-transfer confirmation
# pages, pages that make permanent configuration changes, etc.).
# Sending the `X-Frame-Options` header can also protect your web site against
# more than just clickjacking attacks: https://cure53.de/xfo-clickjacking.pdf.

# | Reflected Cross-Site Scripting (XSS) attacks |
# ------------------------------------------------------------------------------
# (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 IE 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.: IE), 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.
