who is viewing my page?

how to keep record of who is viewing the page? In my case there is no login but I want to record some info. What can I record?.

You need to use a serverside script to record info, you can record IP addy and browser info. If you scroll to the bottom of this page you will see a ball in a box. it goes here.
You can see what they track.

can you give me sample code for that.

You can not store it with JavaScript, you are going to need a server side language.
