<title>Security note</title>
<p>Sending error pages without a specified character set may
allow a cross-site-scripting attack for existing browsers (MSIE)
which do not follow the HTTP/1.1 specification and attempt to
"guess" the character set from the content. Such browsers can
be easily fooled into using the UTF-7 character set, and UTF-7
content from input data (such as the request-URI) will not be
escaped by the usual escaping mechanisms designed to prevent
cross-site-scripting attacks.</p>
