[INFO] HttpMethodDirector - Failure authenticating with NTLM <any
realm>@172.16.100.16:8080

When I tried the with the code changes as
In processRedirectResponse {
        method.getHostAuthState().invalidate();
        I added the below line, 
        method.getProxyAuthState().invalidate();
       }
       This works
Thanks,
RajK
