Data of previous form gets submitted on refersh

Hello ,
I am developing a web based application using jsp and servlet. In this application I have login page, validation servlet if user is valid user I called the another servlet which retrieves the form names from database and this data is send to jsp page where use has to select form. On the submit event of this jsp page again I call one servlet which retrieves form data from database. And send data to next jsp page on this jsp page user has to fill the form and on submit action i have called servlet to update data into database. And after successful submission of data I have redirected the response to previous servlet which retrieves next form data from database. But if here I press refresh button the previous form data gets submitted into database with new form.

Can any one please help me to solve this problem?
I have use the no cache control in all my jsps and servlets.

Thanks in advance

Are you sure that the last action is a redirect? it sounds like you are leaving the POST as the last action.

Thanks for response Bear Bibeault.

I used RequestDispatcher to go back to previous servlet.
