Dear Pludi, Thanks for the code. But the problem is somewhat different and I already know how get or post works and how to run the scripts.
So let me explain you in a different manner. I dont want to use JSP and want to implement in html.

Lets take one example.... I have two html pages... first one is a login page through which a user will be able to login and then only will be able to see the second html page... and noone can able to directly access the second page without loging in... The problem is the login page that I want to design in such a way that it will give freedom to the user to change its password... and how I can use session in html pages..... Thanks and hope this time you can understand my problem more clearly
