in thread cgi page not showing

Well, as I said, you cannot call an object method if the object does not exist and its values aren't set, so simply try this instead :-)

my $cgi = new CGI; # get the User my $user = new GWAK::User(); # did it work ? if (!$user) { # if not go to login page print $cgi->redirect("insert your login_url"); } else { # or proceed print $cgi->header(); ... }
caedes is right, since you once write a header you cannot write a second one, but in my experience a mistakenly written second header would then just occur as plain text, but that might differ depending on the default mime-type setting of the webserver.

    He doesn't call the object method $user->redirect_to_login, but the subroutine GWAK::User->redirect_to_login which should work even when the creation of the $user object failed.

    Aside from this, it would be very helpful if the relevant parts of the GWAK module were provided here.

      Correct, but then he is using the method 'errstr' which I guess should return an error string, which must fail, cause it was not populated with a value. So at least it could return 'undef', does it?
