What happens when you type a URL in the browser and press enter?

요약:

1. You type maps.google.com into the address bar of your browser.

2. The browser checks the cache for a DNS record to find the corresponding IP address of maps.google.com.

3. If the requested URL is not in the cache, ISP’s DNS server initiates a DNS query to find the IP address of the server that hosts maps.google.com.

4. The browser initiates a TCP connection with the server.

5. The browser sends an HTTP request to the webserver.

6. The server handles the request and sends back a response.

7. The server sends out an HTTP response.

8. The browser displays the HTML content (for HTML responses, which is the most common).
