Stripes XSS Interceptor

Stripes XSS Interceptor escapes all the parameters that Stripes binds during its Validation & Binding phase using a wrapped request object (a convenient implementation of the HttpServletRequest interface). The code follows the XSS (Cross Site Scripting) security guidance posted at Open Web Application Security Project (OWASP).

NOTE: Parameters gotten manually through request.getParameter() are not sanitized.

This project is an update of the excellent XSS filter from Jeff Ferber and contain the following changes:

• All external dependencies have been removed except for Servlet API and Stripes Framework.
• The class sun.text.Normalizer has been replaced with the newer java.text.Normalizer shipped with Java SE 6. Please read Why Developers Should Not Write Programs That Call 'sun' Packages.
