I tried what u have explained...But it didnt work
I am using "MODx Revolution 2.0.7" and Login package.
i have created 2 sub domains using contexts.
and i tried to log in to all the contexts at same time using as u have suggested.
[[!Login? &contexts=’web,sub1,sub2’]]
but it didnt worked, so i added "session_cookie_domain" setting with value ".domainname.com"
but nothing works...
adding "session_cookie_domain" even effects MODx manager login...it doesnt allow me to login sometime...it behaves like strange.
What could be other way to share session
