I have one multisite craft installation, where the different languages for the sites use different domains:
en -> domain.com
de -> otherdomain.com ..
Users can log in via frontend. Now if users log in and change the language, they get logged out.
i cannot use the defaultCookieDomain setting, because i dont have the same root domain.
According to this post, due to cross-domain restrictions, sites not sharing a root domain are not allowed to receive/read each other's cookies.
Is there another way of sharing the user's CraftSessionId cookie and thus preventing the user being logged out after changing the language?
