In that email from Mike that you pointed to, he pointed at how to do it 
(while also explaining why it's not the default).

You need to set an expiration date on the MV_SESSION_ID cookie so it will 
persist after the browser is closed.

You can do this by setting a GlobalSub in your interchange.cfg like this 
(to make the cookie last 1 week, for example):

GlobalSub <<EOR
sub set_cookie_expire {
     $Vend::Expire = Vend::Config::time_to_seconds('1 week') + time();
     return 1;

And then running it on every page load by setting an Autoload in your 
catalog.cfg like this:

Autoload set_cookie_expire
