I have one page, called page1.html.
I visited page1.html first, then I visited another page.
What javascript code can I place in page1.html, so when someone hit BACK
button to go back to page1.html, he/she should see an alert box states that
"you hit BACK" on page1.html ?

p/s : I only want to use javascript, no post or get method.

No you are not able to see the history, it is a security feature to keep others from knowing the site you just came from, forward or back in the history.

Cookie or server side processing and tracking will need to be set up.
