How to share session across two web applications deployed in two different tomcat instances

I have two different web applications running on two different instances of tomcat. I need to be having a common page with links to both the applications. But I should be able to log in only once and should be able to access links in the other application without being asked to login again.
Is there a way to do it ?

Answer

You can use a token parameter, where the token could be the username/some credentials encrypted. You can verify the credentials are correct in the 2 apps.

An alternative, if your applications are under the same domain would be set cookies and recreate the session from them.
