 Spring Session provides transparent integration with `HttpSession`.
 This means that developers can switch the `HttpSession` implementation out with an implementation that is backed by Spring Session.

 Fortunately both `HttpSession` and `HttpServletRequest` (the API for obtaining an `HttpSession`) are both interfaces.
 This means that we can provide our own implementations for each of these APIs.
 
 NOTE: This section describes how Spring Session provides transparent integration with `HttpSession`. The intent is so that user's can understand what is happening under the covers. This functionality is already integrated and you do NOT need to implement this logic yourself.

 By passing in a custom `HttpServletRequest` implementation into the `FilterChain` we ensure that anything invoked after our `Filter` uses the custom `HttpSession` implementation.
 This highlights why it is important that Spring Session's `SessionRepositoryFilter` must be placed before anything that interacts with the `HttpSession`.
