What exactly happens after you enter a URL, until you see the site content? There is a well defined flow of actions that the browser does internally, like building the DOM and render trees and painting. There is also a set of optimizations taken to ensure that the web site is presented quickly and smoothly. The rendering of the web site is not a single action by the browser, but a set of small updates and constant reactions to interactions. Looking beneath the surface you'll be surprised by the amount of activity taking place in these milli seconds. Being aware of these internal actions can help us take better decisions in creating a more efficient and robust web sites.
