Explain what happens when you type domain in the browser and press enter

• Resolve IP address of the URL via DNS

• Generate an HTTP request with headers (accept, user-agent, cookie, etc)

• Open an HTTP connection to the resolved IP address

• Send the request to the server

• Receive the response from the server

• Parse response headers

• Depending on the response headers, perform additional operations

• Decompress the response body if it's compressed (e.g. gzipped)

• Parse the HTML code inside the response body

• Resolve any additional resources (images, stylesheets, scripts, etc)

• Start loading those resources via their URLs using the same steps

• Render the HTML as soon as required resources are loaded, continue loading remaining resources in background

• When all the resources are loaded, close the HTTP connection
