Example: Request attributes and session attributes

Request values passed to the JSP or stored in the HTTP session can be referred to from rules. To refer to them in a rule, you must know the variables and their possible values.

The following example profiles news articles as read or unread by the current user, based on the page request generated by a form on a JSP.
