I have set timeout for my asp.net application to 5 minutes, like web.config below:

mode="InProc"
stateConnectionString="tcpip=127.0.0.1:42424"
sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes"
cookieless="false"
timeout="5"


my question is how to automatically redirect to login page (login.aspx) it timeout exceeded.. please advise ..

many thanks in advance
