Package edu.uiuc.ncsa.security.servlet

Class MyTomcatFilter

java.lang.Object

edu.uiuc.ncsa.security.servlet.MyTomcatFilter

All Implemented Interfaces:

javax.servlet.Filter

public class MyTomcatFilter
extends Object
implements javax.servlet.Filter

A really basic filter. Any path that starts with a "/pages" or a "/static" is intercepted and passed to the default java servlet that Tomcat runs. Your static content goes into the directory named static and your other content is served from the directory called pages. This fixes a feature of Tomcat 6 that allowed the default servlet to serve up static content from the top-level directory including possibly sensitive information. Tomcat 7 prohibits this, so we have to route static requests ourselves.

Note that this (or some other similar filter) must be specified in your deployment descriptor (web.xml file) in order to serve up static pages.
