Evening monks, I'm after some of your wisdom.

I have a Mojolicious lite app that works as I would expect for a single user. However, if two users are accessing it at the same time, the value of $router is changing depending on who submitted the request last.

For example, if user A submits the form to query 'RouterA' then the information is displayed for that router. However, when user B then submits the form to query 'RouterB', the session for user A and user B displays the information for 'RouterB'. I figure it must be since I am declaring $router (and other things) globally but I'm not sure how to store this and pass it around the different routes I have...

my ( $router, $cfg, $ip );

get '/' => sub {
  my $c = shift;
  $c->render( template => 'index' );
};

post '/' => sub {
  my $c = shift;
  ($router) = $c->param('router');
  app->log->info("Router $router");

  $cfg = get_config($router);
  $ip = $cfg->get_ip();

  $c->render(
    template => 'result',
    router   => $router,
    ip => $ip,
);
} => 'index';

get '/info' => sub {
  my $c      = shift;
  $c->render(
    template => 'result',
    router   => $router,
    ip => $ip,
);
};

get '/cards' => sub {
  my $c     = shift;
  my %cards = $cfg->get_cards();

  $c->render( template => 'cards', router => $router, cards => \%cards
+ );
};

app->start;

The reason I have globally declared the variables is so I can pass them between the different routes and have the value of $router preserved and displayed on each resultant HTML page. Any help greatly appreciated as I'm scratching my head with this one!
