Guys,
I am using several sub-domains that all point to the same app (they
cause different content to be displayed, depending on the sub-domain).
For example, I have:
content1.myapp.com
content2.myapp.com
content3.myapp.com
...etc...
I need the session data to be shared across these subdomains, so that
when a user is clicking around the app, crossing across sub-domains,
they won't lose the session state (e.g., if they're logged in, etc).
I understand that Tomcat uses session cookies to associate server
session with the client request. And I understand that the default
behavior of this causes these session cookies to be specific to a
domain/sub-domain.
My question:
How can I make the session cookies get written so that they are relevant
to ALL sub-domains under the main domain. I have read a few things that
say that if you set the domain of the cookie to be ".mydomain.com", it
will be associated with all sub-domains of that primary domain. But,
not sure how to do this since tomcat has some built in way of setting
these cookies... I saw something with valves, but need more info.
Any help here, or suggestions for a different approach altogether for
sharing session state across sub-domains, would be very much appreciated.
thx,
steve
