Anusha, set response headers in a filter like

HttpServletResponse res = (HttpServletResponse) response;
res.setHeader("Cache-Control", "no-cache, no-store, must-revalidate");
res.setHeader("Pragma", "no-cache");
res.setDateHeader("Expires", 0);
chain.doFilter(request, response);

or you can set it in your jsp as meta tags also.
