This script displays information about your web browser including version, your computer's platform, whether Java is enabled or not, how many pages you've visited, and screen resolution.
Use this script to show visitors several interesting details about their screen - the screen width, screen height, and screen resolution of their browser window. You might use this script to suggest that your visitors expand their browser to a larger size before accessing your site, etc.
It is surprising to know that a web page can actually know how many pages you have been to this browser session. That is exactly what this script does.
