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

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
