Building efficient websites with AJAX
Before rendering a website, the browser and web server go through a number of steps (Figure 1):
- The browser sends a page request to a web server.
- The server processes the request and serves up the HTML text and images. This might take a couple of seconds if the load is heavy. The network transmission speed decides how fast the content is delivered. The required time is still noticeable on fast intranets, however.
- Finally, the browser reads the response and displays the page. The same sequence is repeated for each image before the browser can render the final version of the page.
