All I can find in the Tomcat 5.5 docs is:
Set to true if you want calls within this application to ServletContext.getContext() to successfully return a request dispatcher for other web applications running on this virtual host. Set to false (the default) in security conscious environments, to make getContext() always return null.
I've found some forum posts that comment that setting crossContext=true
also enables sharing the session object between different web applications, but I'm not able to find any official docs stating this.
Is there a relation between Servlet.getContext() and the ability to share session state between different web applications?
What does the crossContext
attribute really do in Tomcat?
