Before this release of J2EE agents, information for HTTP headers, request attributes, or cookies was retrieved, or sourced, solely from profile attributes. Now, this information can also be sourced from session properties.
Benefit - Support for Fetching User Session Attributes: The benefit of this feature is that session properties can be more effective for transferring information, especially dynamic information. Prior to this release, agents could only fetch users’ profile attributes, which tend to be static attributes. However, session attributes allow applications to obtain dynamic user information when necessary.
