I uploaded to pastebin. It is quite specific to my particular needs so
not really suitable for distributing as modules on github. I'm sure it
can be adapted without too much trouble, and might help you to write
your own. For example, I like to cache the session id (sid) in the
users table in my database. You could simply remove all the database
specific parts from Abstract.pm and adapt it to your needs.

MyApp::Session::Abstract - http://pastebin.com/RfUzQQi3
MyApp::Session::Storable - http://pastebin.com/EKnrs1mA


use MyApp::Session::Storable;

post '/login' => sub {
    # authenticate user
    if ($authenticated) {
        my $session = MyApp::Session::Storable->new(username =>

before_sub {
    my $session = MyApp::Session::Storable->get_session;
    if (defined $session) {
        var session => $session;

# In each route handler
my $session = vars->{session};
if ($session) {

# The session object is a hashref, easy to add session data to it
$session->{lastvisit} = localtime;

# Flush it

# Delete it
