    Read through the documentation for AbstractAuthenticationProcessingFilter (based on your earlier question, I guess this is the class that your custom filter extends), the abstract method to implement is attemptAuthentication, which receives HttpServletRequest and HttpServletResponse as parameters:

    Parameters:
    request - from which to extract parameters and perform the authentication
    response - the response, which may be needed if the implementation has to do a redirect as part of a multi-stage authentication process (such as OpenID).
