I'm astonished at how difficult sessions are to get working, even for an experienced Perl programmer like me.

I'm not :) HTTP is complicated enough, and then you have to deal with implementation details of and

CGI::Session->new will try to load a session first, and only create a new session if it fails to load one

The thing is, since in CGI protocol, cookies are retrieved via $ENV{HTTP_COOKIES}, if there is a cookie set, CGI::Session will always load an existing session, because (or will always read $ENV{HTTP_COOKIES}

Hopefully you have read Basic cookie management (May 01) by now,

but here is how you fix your program without changing the program flow,

you delete the session if you can load it, then you create a new one

if ($action eq 'login') { $session = CGI::Session->load( "driver:File", undef, $dsn_args ); eval { $session->delete; $session->flush; }; $session = CGI::Session->new( "driver:File", undef, $dsn_args ) or die CGI::Session->errstr; }
