In this chapter, we understood the importance of throttling rules and how we can combine them with authentication and permissions in Django, the Django REST framework and RESTful Web Services. We analyzed the throttling classes included in the Django REST framework out of the box.

We followed the necessary steps to configure many throttling policies in the Django REST framework. We worked with global and scope-related settings. Then, we used command-line tools to compose and send many requests to test how the throttling rules worked.

We understood versioning classes and we configured a URL path versioning scheme to allow us to work with two versions of our RESTful Web Service. We used command-line tools and the browsable API to understand the differences between the two versions.

Now that we can combine throttling rules, authentication and permission policies with versioning schemes, it is time to explore other features offered by the Django REST framework and third-party packages to improve our RESTful Web Service and automate tests. We will cover these topics in the next chapter.
