Concurrent web requests

In the context of concurrent programming, we can see that the process of making a request to a web server and obtaining the returned response is independent from the same procedure for a different web server. This is to say that we could apply concurrency and parallelism to our ping test application to speed up our execution.

In the concurrent ping test applications that we are designing, multiple HTTP requests will be made to the server simultaneously and corresponding responses will be sent back to our program, as shown in the following figure. As discussed before, concurrency and parallelism have significant applications in web development, and most servers nowadays have the ability to handle a large amount of requests at the same time:
