Already lots of questions available regarding this. But there is no perfect answer I can find for me. So once again I am asking this question.
I want to share my session on multiple domains(not sub domain) like waht google.com is doing. When we login on google account at the same time we also login gmail.com, youtube.com and other google domains. And same when log out from any domain than also log out from every domain. This same functionality I want to do in my application.
With this functionality also there are some restrictions. I can not use database sessions. Also I can not store cookie for any information.
Give me suggestions...
