Answer from AI
When entering a URL in the browser's address bar and confirming navigation, the following processes occur:
-
URL Parsing — the browser analyzes the entered address, identifying the protocol, domain name, path, and parameters.
-
Cache Check — the browser checks if a saved version of the page exists in the local cache.
-
DNS Query — if the IP address for the domain is unknown, the browser sends a request to the DNS server to obtain the IP.
-
Establishing Connection — the browser establishes a TCP connection with the server using the obtained IP, usually through port 80 (HTTP) or 443 (HTTPS).
-
TLS Handshake — if HTTPS is used, a secure connection is established.
-
Sending HTTP Request — the browser sends a request to the server (GET, POST, etc.).
-
Receiving Response — the server returns a response with a status code, headers, and body.
-
Processing Response — the browser parses the HTML, loads additional resources (CSS, JS, images).
-
Page Rendering — the browser constructs the DOM, CSSOM, executes scripts, and displays the page to the user.
