How Browsers Load a Web Page Understanding how a browser loads a web page is essential for anyone who works with websites—developers, designers, and even content creators.  When you understand this workflow, you can optimize performance, fix rendering delays, and improve user experience and Core Web Vitals. 1. Step 1 — URL Input & DNS Lookup The browser loading journey begins the moment a user types a URL like: https: //example.com 1.1 What happens next? The browser checks its internal cache for a DNS record. If not found, it queries the operating system DNS cache. If still not found, the OS sends a request to a DNS resolver. The resolver returns the IP address (e.g., 93.184.216.34 ) of the server hosting the website. 1.2 Why it matters DNS lookup adds latency. Slow DNS affects Time to First Byte (TTFB). 2. Step 2 — Establishing a TCP & TLS Connection 2.1 TCP Handshake After DNS lookup, the browser must establish a connection using the TCP ...
