What are HTTP Response Headers and why do they matter?

Understanding the significance of HTTP response headers

HTTP response headers are essential components of server communication that provide important information to the browser, enabling the proper rendering of webpages.

How do HTTP response headers impact web performance?

HTTP response headers directly influence the speed, security, and functionality of a website. Properly configured headers can optimize loading times and enhance security measures. Conversely, incorrect or outdated headers can lead to issues like slow loading speeds, security vulnerabilities, and improper page rendering.

Some important HTTP response header fields to monitor include Content-Type, Cache-Control, Set-Cookie, and X-Frame-Options, each serving a specific purpose in defining the behavior of the web server.
