All
I have protected my struts application with the following directives from
the web.xml file for the application (see below). This works fine. The
browser displays a popup alert requesting the authentication info. I have
left the tomcat session timeout to it's default value (30 mins I think). I
can program each page (via the template) in my application to check for the
existence of a attribute that the application establishes soon after logon
and then redirect the browser to the logon page (logon.do). If I try this
I get a 'request has already been committed' error. I think the browser
does not know that the server session has been terminated. What do I need
to do, so that the application forces the browser to re-authenticate the
user on session timeout?
