How to fully logout? Spring Security -

how can logout? have in xml file:

<security:logout logout-url="/logoutme" /> 

and when enter /logoutme url not logged out - on controller added:

securitycontextholder.getcontext().getauthentication().getname() 

and added name modelandview , display on page, , there still username, not anonymoususer before logging in.

how logout totally? i've tried create own logoutsuccesshandler implementation with:

securitycontextholder.clearcontext(); 

but.. doesnt seem work

this method spring security calls default on logout(from securitycontextlogouthandler class):

public void logout(httpservletrequest request, httpservletresponse response, authentication authentication) {     assert.notnull(request, "httpservletrequest required");     if (invalidatehttpsession) {         httpsession session = request.getsession(false);         if (session != null) {             logger.debug("invalidating session: " + session.getid());             session.invalidate();         }     }      if(clearauthentication) {         securitycontext context = securitycontextholder.getcontext();         context.setauthentication(null);     }      securitycontextholder.clearcontext(); } 

have tried use default, provided spring security logout url /logout? or have customize things?
