I was very confused about using "requset" in jsp/servlet program. I think the parameter/values of hidden input field in a form will everytime be submitted to my
servlet. But when I press the back button and then submit, in my servlet I get the parameter values which is belong to the page before I push back button. In these two pages, there are the same input field. Who can give me an clarification or some advice or a link?
Thanks very much.
