        The Microsoft Anti-Cross Site Scripting Library V4.3 (AntiXSS V4.3) is an encoding library designed to help developers protect their ASP.NET web-based applications from XSS attacks. It differs from most encoding libraries in that it uses the white-listing technique -- sometimes referred to as the principle of inclusions -- to provide protection against XSS attacks. This approach works by first defining a valid or allowable set of characters, and encodes anything outside this set (invalid characters or potential attacks). The white-listing approach provides several advantages over other encoding schemes.

        This release addresses a bug in the HTML sanitizer which stripped attributes and addresses Web Forms incompatibility in the HTML encoding libraries.

        This is the last release that will include the HTML sanitizer.
