Abstract

   This document describes the "hxxp" and "hxxps" URI schemes, which are
   widely used by the security community to obfuscate an http or https
   URI to avoid being accidentaly interpreted and loaded by a web
   browser or user-agent.

1.  Introduction

   This document describes the "hxxp" and "hxxps" URI schemes, which are
   widely used by the security community to obfuscate an http or https
   URI to avoid being accidentaly interpreted and loaded by a web
   browser or user-agent.

   These schemes are used in case the resource is dangerous and there is
   security risks on being automatically processed by an application,
   such a pre-loading mechanism in web user agents.  It also prevents
   the creation of "clickables" areas in user interfaces, which could
   detect http or https URIs automatically.

   The purpose of this registration is to document its use, prevent any
   registration of this scheme in the future, explicitly recommend to
   web application developers to never act with this URI schemes in any
   way, and provide a safe method for the security community to share
   malicious information.  These schemes must not be treated as an http
   or https schemes, and must not be identified as web resources.  Its
   consumption is only for humans and documentation, and should be
   handled with caution by security professionals.

1.1.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
