From 98fd9df4c4a04554fd2f707ca9ea2d674fad984d Mon Sep 17 00:00:00 2001
From: Micael Karlberg <bmk@erlang.org>
Date: Thu, 15 Sep 2011 09:43:48 +0200
Subject: Updated http-server to make sure URLs in error-messages are
 URL-encoded. Added support in http-client to use URL-encoding. Also added the
 missing include directory for the inets application.

OTP-8940

[httpd] Prevent XSS in error pages.
Prevent user controlled input from being interpreted
as HTML in error pages by encoding the reserved HTML
characters.
Michael Santos
