Summary

In this chapter, we 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 of HTTP response status codes, each indicating a different concept regarding the communication between the server and its client. By considering the status codes that are received from different websites, we can write a ping test application that effectively checks 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 several considerations in mind when making concurrent web requests.

All in all, the exercise we just went through in this chapter will prove useful in helping us approach the general problem of converting a sequential program into its concurrent version. The simple ping test that we have built could also be extended to...
