[S2] how to prevent the results pages get saved in the browser's cache

[Gabriel Belingueres]

Hi,

Which is the best (right?) way of setting the HTTP headers in a S2 app
to prevent the browser to cache the result pages?

I'm testing right now with a servlet filter which match all /* URLs
but the back button is still working (i.e. the previous page is stored
in the browser cache).

Here is the filter code:

 public void doFilter(ServletRequest request, ServletResponse response,
                      FilterChain chain) throws IOException, ServletException {

   HttpServletResponse res = (HttpServletResponse) response;

   res.setHeader("Cache-Control", "no-cache");
   res.setHeader("Pragma", "no-cache");
   res.addDateHeader("Expires", 0);

   chain.doFilter(request, response);
 }

Am I doing something wrong?

It is best to implement it as a servlet filter? or as an interceptor?
any other way?

TIA,
Gabriel
