-# (1) Try to re-enable the cross-site scripting (XSS) filter built into most
-#     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. Therefore, it's better
-#     to inform browsers to prevent the rendering of the page altogether,
-#     instead of attempting to modify it.
