This course will guide you through how a client communicates with a server. You'll learn about HTTP's request and response cycle, dig into HTTP headers and verbs, distinguish HTTP/1 from HTTP/2 capabilities, all while experiencing the importance of security by digging into the details of HTTPS. Throughout the course, you'll learn both security best practices, as well as ways to improve the performance of your web apps. We'll provide you with handcrafted servers where you'll diagnose problematic server setups, issues with SSL certificates, and even have a chance to hack an example bank website to transfer funds.
Learn how a client communicates with a server, including HTTP’s request and response cycle, HTTP/2 and HTTPs.
[
Typically, web developers do not work directly with underlying platform of HTTP. But knowing how information is transferred across the wire is vital to creating efficient and professional apps. This course will dig into the ins and outs of application performance as well as cover common security pitfalls and how to prevent them.
