Com. Browser Page Processing When a browser loads a page, it's not performing a batch process. Users don't close their eyes after they enter a URL and open them again when the browser has finished loading the page. Browsers do what they can to overlap activity on multiple network connections with page parsing and rendering to the screen. The steps that browsers follow are often extremely visible to users and can have a significant impact on both perceived performance and total page load time. Network Connections and the Initial HTTP Request To retrieve a web page, browsers start with a URL.

The browser parses the response and renders it to the screen in parallel with the ongoing network activity, queuing and requesting content from other URLs in parallel as it goes. Rather than getting too sidetracked with the variations from one browser to another, my focus here will mostly be on Internet Explorer 9 (IE9, or just IE). Other browsers work similarly, although there are definite differences from one implementation to another. With Firefox, users can set parameters that change some of the details of how it processes pages, so the page load experience may not be 100 percent identical from one user to another, even when they're using the same browser.
