Introduction

This article is a guide to Cross Site Scripting (XSS) testing for application security professionals. This cheat sheet was originally based on RSnake's seminal XSS Cheat Sheet previously at: http://ha.ckers.org/xss.html. Now, the OWASP Cheat Sheet Series provides users with an updated and maintained version of the document. The very first OWASP Cheat Sheet, Cross Site Scripting Prevention, was inspired by RSnake's work and we thank RSnake for the inspiration!
