Quiz:

Try to replace request.getRequestURI() in #commence method with custom value retrieved from request attribute:
org.springframework.security.web.access.channel.RetryWithHttpsEntryPoint
org.springframework.security.web.access.channel.RetryWithHttpEntryPoint

Try to override org.springframework.security.web.DefaultRedirectStrategy, but reuse complex logic in org.springframework.security.web.DefaultRedirectStrategy#calculateRedirectUrl

Remember proper encapsulation is important to keep code complexity down to a minimum. In general, Spring Security favors composition over inheritance. For this reason, you will not find a lot of hooks via protected methods. This is especially true in implementations of interfaces with only a single method.
