Summary


In this chapter, we have learned about the basics of HTML and web requests. The two most common web requests are GET and POST requests. There are five main categories for HTTP response status code, each indicating a different concept regarding the communication between the server and its client. By considering the status codes received from different websites, we can write a ping test application that effectively checks for the responsiveness of those websites.

Concurrency can be applied to the problem of making multiple web requests simultaneously via threading to provide a significant improvement in application speed. However, it is important to keep in mind a number of considerations when make concurrent web requests.

In the next chapter, we will start discussing another major player in concurrent programming: processes. We will be considering the concept of and the basic idea behind a process, and the options that Python provides for us to work with processes.
