RE: how to cache lists?

[Greg Reddin]

< The above approach is fine if you want to have cache within a single

< different web applications, you can use a Startup class like what Weblogic
< provides. You can have your cached data as instance variables of  your
< startup class and every web application should be able to access that.

Or you could keep them in an intermediate store like LDAP.
