Web Policy Agent works similarly as the J2EE Policy Agent, except for a slight variance. No CDSSO Redirect Servlet exists on the web policy agent because the agent is a NSAPI plugin. Instead, the web policy agent is invoked via a URL parameter called sunwMethod. As a result, the web policy agent combines the above steps 13-16 into a single step without the extra redirection in Step 14. For more details, please refer to the section "Web Policy Agent Sample Protocol Exchange" in this document.
