+        <p>
+          In order to maximize the extensibility, Reverse Proxy Module is implemented with
+          the <a href="http://en.wikipedia.org/wiki/Chain-of-responsibility_pattern" target="_blank">Chain
of Responsibility pattern</a>
+          by using <a href="http://commons.apache.org/proper/commons-chain/" target="_blank">Apache
Commons Chains</a> module.
+        </p>
+        <p>
+          By default, <code>org.apache.portals.applications.webcontent2.proxy.builder.DefaultProxyProcessingChainBuilder</code>
+          initializes and adds all the common commands to the internal reverse proxy service
component.
+          However, you can always modify the chains of the commands in your extended servlet/filter/portlet
classes.
+        </p>
+        <p>
+          For example, <a href="https://svn.apache.org/repos/asf/portals/jetspeed-2/applications/j2-admin/trunk/src/main/java/org/apache/jetspeed/portlets/sso/SSOReverseProxyServlet.java"
target="_blank">org.apache.jetspeed.portlets.sso.SSOReverseProxyServlet</a> in j2-admin
project
+          extends <code>org.apache.portals.applications.webcontent2.proxy.servlet.SimpleReverseProxyServlet</code>
+          in order to replace the default <code>org.apache.portals.applications.webcontent2.proxy.command.InitHttpRequestCommand</code>
+          by <code>org.apache.jetspeed.portlets.sso.SSOInitHttpRequestCommand</code>.
+          Also, <code>SSOReverseProxyServlet</code> customizes the default <code>HttpClientContextBuilder</code>
by a custom one,
+          <code>JetspeedHttpClientContextBuilder</code>, in order to build custom
authentication states
+          based on the Jetspeed SSO Site credentials.
