Class BasicProcessingFilterEntryPoint

java.lang.Object
  extended by org.acegisecurity.ui.basicauth.BasicProcessingFilterEntryPoint
All Implemented Interfaces:
AuthenticationEntryPoint, org.springframework.beans.factory.InitializingBean

public class BasicProcessingFilterEntryPoint
extends Object
implements AuthenticationEntryPoint, org.springframework.beans.factory.InitializingBean

Used by the SecurityEnforcementFilter to commence authentication via the BasicProcessingFilter.

Once a user agent is authenticated using BASIC authentication, logout requires that the browser be closed or an unauthorized (401) header be sent. The simplest way of achieving the latter is to call the commence(ServletRequest, ServletResponse, AuthenticationException) method below. This will indicate to the browser its credentials are no longer authorized, causing it to prompt the user to login again.
