Cross site scripting (XSS) is security vulnerability in World Wide Web. Information sharing between computers is increasing day by day. web security is most important topic to be discussed. Web applications often use cookies to maintain authentication between the user and web application where XSS attack is a popular attack to steal cookies between client and server. By using XSS technique, attacker insert malicious script onto the application�s output. Some Web Application Vulnerabilities like Cross Site Scripting (XSS or CSS) and SQL Injections are happened because of poor input validation. In this paper we are proposing a new and light weight technique for �Cookies Alteration�. This technique aims to repay the cookie useless for the attacker. Our technique is to implement a proxy that will recreate the cookie that is sent back and forth between the browser (Client) and server (web application). If attacker steals cookies then these cookies will be worthless for him. Our aim is not only to protect cookies but render the user�s data secure.
