hi guys<BR><BR>i am having a login screen and a home page. if the user enters a valid username and password then the home page will be displayed. once the user clicks the LOGOUT button in the homepage then he should not be able to go back to the homepage. he should be always redirected to the logon page. somebody please help me to do this. one more thing is if the user clicks the BACK button in the browser then he should be redirected to the logon page
