It is not good practice to store large object graphs in
HttpSession. This can severely affect the performance of a WebSphere
application.
Look for alternatives like an application-specific JDBC™ framework that
can augment or replace HttpSession for storing servlet state data.
Application design for performance and scalability requires consideration
of servlet state data.
If your application requires a large amount of servlet data, consider
application-specific alternatives that either augment or replace the use
of HttpSession.
