From Browser to Server : The Journey of an HTTP Request (Demystifying the Web’s Infrastructure)
The article explains the complex journey of an HTTP request from a browser to a server. It details the various layers of infrastructure involved, including DNS lookup, TCP connection, and client-server architecture. Understanding these processes is crucial for developers to optimize web performance and ensure reliable communication.
- ▪The journey begins with a DNS lookup that translates a domain name into an IP address.
- ▪A TCP connection is established through a three-way handshake to ensure reliable communication.
- ▪The HTTP request is structured with a request line, headers, and an optional body, and follows REST conventions for predictable interactions.
