Optimizing Web App Performance: GZIP, Cookies, and Redirects

Slow loading times can drive users away from your web applications before they even see your content. Many performance bottlenecks happen right at the server level, long before your frontend code finishes executing in the browser. This written course guides you through foundational server-side optimization techniques that every modern web developer must know. By understanding how to inspect response headers, compress assets, and streamline HTTP communication, you will be able to deliver lightning-fast web experiences. What you'll learn: - Understand HTTP response headers and how to verify server-side configurations - Configure GZIP and modern Brotli compression to drastically reduce text asset sizes - Optimize cookie payloads and implement modern attributes like SameSite and Secure - Identify and eliminate redirect chains that delay Time to First Byte (TTFB) - Apply performance-first practices to improve Core Web Vitals and overall user experience You will start by exploring core web performance terminology and analyzing HTTP headers. From there, you will read through practical configuration examples and learn how to audit your web applications using standard developer tools. This course is designed for beginner developers, system administrators, and tech enthusiasts looking to build a solid foundation in web performance without any complex prerequisites.
