[dancer-users] Single login to multiple domains

Hi, I run both the Perl Maven site https://perlmaven.com/ <http://perlmaven.com/> and the Code Maven site https://code-maven.com/ <http://code-maven.com/> on the same Dancer2 application. They even share the database behind. Both also have several language-specific hostnames. e.g. one in Telugu: https://te.perlmaven.com/ I would like to allow my users to log in any of the sites and then be already logged in all of the others. So they won't need to authenticate again. How could I achieve this? Gabor <dancer-users@lists.preshweb.co.uk>
