The simple goal of this lesson is to give you insight into exactly how Spring deals with an HTTP request.
A quick side-note here - one of my goals with this course is to keep it up-to-date.
As I upgrade the Spring versions, there will be small details that are going to be different in the source of the Spring classes, compared to the video. These are very small changes and don't change the overall logic.
Whenever a significant change is release, I always re-record the video lesson.
So just be aware of that.
