Hi,

No. I'm suggesting they be proper filters, per the servlet spec v2.3.
Specifically, you'd have two things that implement javax.servlet.filter:
public class MyAuthenticationFilter
implements Filter {
...
}
public class MyMonitorFilter
implements Filter {
...
}
And then in your web.xml:
<web-app>
...
<filter>
<filter-name>MyAuthenticator</filter-name>
<filter-class>com.mycompany.MyAuthenticationFilter</filter-class>
</filter>
<filter>
<filter-name>MyMonitor</filter-name>
<filter-class>com.mycompany.MyMonitorFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>MyAuthenticator</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>MyMonitor</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
...
<servlet>
<servlet-name>MyMappedServlet</servlet-name>
<servlet-class>com.mycompany.MyServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>MyMappedServlet</servlet-name>
<url-pattern>/MyMappedServlet</url-pattern>
</servlet-mapping>
...
</web-app>
>typed the www.whatever.org/, which one would be invoked? What would
occur
>if the user typed www.whatever.org/MyServlet directly before the

the

Requests for your servlet would be intercepted by both filters before
(and after) the servlet gets them. If you need help on the filter
design / implementation, post that question and we'll be glad to help ;)
