-<p>Filters are new in the <cite>Sun Microsystems Java Servlet
-2.3 Specification</cite>. They enable you to intercept to intercept a
-request before it reaches a resource. In other words, a filter gives you
-access to the HttpServletRequest and the HttpServletResponse objects
-before they are passed on to a servlet.</p>
-<p>Filters can be very useful. For example, you can write a filter
-that records all incoming requests and logs the IP addresses of the
-computers from which the requests originate. You also can use a filter
-as an encryption and decryption device. Other uses include user
-authentication, data compression, user input validation, and so on.</p>
-<p>You also can put a set of filters in a chain. The first filter in
-the chain will be called first and then pass control to the second
-filter, and so on. Filter chaining ensures that you can write a filter
-that does a specific task but adds some functionality in another filter.</p>
-<p>When writing a filter, you basically deal with the
-following three interfaces in the javax.servlet package:
-<ul>
- <li><b>javax.servlet.Filter:</b> represents the
- life-cycle of the filter.</li>
- <li><b>javax.servlet.FilterConfig:</b> represents the
- configuration of the filter.</li>
- <li><b>javax.servlet.FilterChain:</b> object provided by
- the servlet container to the developer giving a view into the
- invocation chain of a filtered request for a resource.</li>
-</ul></p>
