I have seen lots of example of going back to previous page using back button but none has described how to avoid page expired error.

I have JSP page(b.jsp) with the following code to go back to the previous JSP page(a.jsp)

but when i click on this button, instead of getting the previous JSP page I am shown this error

Webpage has expired Most likely cause: •The local copy of this webpage is out of date, and the website requires that you download it again
.

How do i avoid this error. I heard of Caching, but I have no idea where to put in the JSP page and how. Any advice would be very helpful
