Class HttpServletRequestWrapperFilter

java.lang.Object
  org.jasig.cas.client.util.AbstractConfigurationFilter
      org.jasig.cas.client.util.HttpServletRequestWrapperFilter

All Implemented Interfaces:

javax.servlet.Filter

public final class HttpServletRequestWrapperFilter
extends AbstractConfigurationFilter

Implementation of a filter that wraps the normal HttpServletRequest with a wrapper that overrides the following methods to provide data from the CAS Assertion:

• HttpServletRequest.getUserPrincipal()
• HttpServletRequest.getRemoteUser()
• HttpServletRequest.isUserInRole(String)

This filter needs to be configured in the chain so that it executes after both the authentication and the validation filters.

3.0
