Hi,
You need to add a return statement at the end of the redirect. So it will
look like below
*response.sendRedirect("/InfraPortal/login.jag");*
*return;*
The issue is happening even though you redirect to the login page, flow in
the sane page will execute and you might have another redirect at the end.
Regards,
Venura
