What happens behind-the-scenes if you enter a URL address to the browser address bar and hit enter?

Answer
The browser creates a HTTP request and sends it to the server. The server then responds back and sends the web page data (HTML code).
- The URL address in HTTP requests defines which web page will be downloaded
- The method used in HTTP request is GET, because no form data are submitted (otherwise POST method would be used)
- The status code returned in response defines whether the request succeeded or whether it failed
Excercise
- Open Chrome browser and press F12 to open Chrome DevTools. Select the Network tab in DevTools.
- Enter the URL https://www.bettercoder.io to the address bar and hit enter.
- Analyze the following
- Did the request succeeded or failed? What status code was returned?
- What data was returned from the server?
- What was the size of the data returned from the server?
- How many requests were sent by the browser
