Mix protocols transparently in Web applications To maintain the security of sensitive data as it travels over the Internet to or from the browser, Web applications often rely on Secure Sockets Layer. The secure Webpages and processes that transmit sensitive data utilize HTTP over SSL (HTTPS) rather than the usual HTTP. Integrating SSL into a Web application should prove seamless and simple to implement as well as maintain. This article explores typical SSL implementations and develops an SSL solution using the J2EE servlet redirect mechanism to protect sensitive data transmission. It also develops an overall solution combining JavaServer Pages custom tags and an application-specific servlet base class.  |
