Abstract
In this chapter, we will discuss two similar technologies: valves and filters. These technologies were invented for the purpose of intercepting requests for one or more web applications. The first, Tomcat Valve, is a proprietary Tomcat technology. The second, servlet filters, is a server-independent technology that was introduced as part of the Java Servlet specification (since version 2.3). Both of these technologies are used to process HTTP requests and response objects.
