1. Entering a URL:
The user enters a URL into the browser.
The browser breaks down the URL into parts to obtain information about the protocol, domain name, port, path, and parameters.
2. Resolving the IP address:
The browser checks the DNS cache to find the IP address associated with the domain name.
If the IP address is not found in the cache, the browser sends a request to the DNS server.
The DNS server responds with the IP address associated with the domain name.
3. Establishing a connection:
The browser uses the IP address and port to establish a TCP connection with the web server.
4. Sending an HTTP request:
The browser sends an HTTP request to the web server.
The request contains a method (GET, POST, PUT, etc.), the path to the resource, the HTTP version, and other headers.
5. Receiving an HTTP response:
The web server processes the request and sends an HTTP response.
The response contains a status code, headers, and the response body.
6. Closing the connection:
The browser closes the TCP connection with the web server.
7. Displaying the result:
The browser processes the response body and displays the result to the user.
