Back button issue

[venkatesh pendharkar]

Hi all,
I am developing currently an online shopping website. On this website, on some of the pages I want to disable the browser back button . If not disable, then at least I want show an alert on back button. I made a lot of search on google, but everywhere I found that it is not possible to disable back button or know the back button alert. Can anyone help me out with any suggetions?
Also I tried to clear the history for the pages for which I want to disable the back button. But my code works in IE & not in other browsers. So it will be great if someone can give me a code that will not save the current page in the history for all the browsers?
Thanks in advance.
