Question

Hi Experts,
I have done a web based application using JSF..it contains log in and logout page.I am maintaining a session if I logged in and if I logged out that session will be expired.so if I again press the back button after logged (session Expires)I am getting an confirm dialogbox from firefox which ensures whether to resend post data.if I pressed ok I am getting exceptions.I would lik to know how to impede this confirm dialogbox or to redirect to an other page when i pressed ok button.I dont know where and how to invoke the code for this regardings.pls suggest me how to resolve this issue...

Hi,
Thanks for ur suggestions..But I have already implemented
public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain)
}and redirected it to an other page...But I am getting this confirm dialog box only in the rare occasions and if I pressed ok button I am getting exceptions..I have seen some sites where if this confirm dialog box came and if the user pressed ok button they will again redirect to an another page.please give neccessary inputs to handle this issue..The point of the filter is to detect the situations which will cause exceptions and issue a redirect in those cases.
