An apparatus and method provide persistent data during a user session on a networked computer system. A global data cache is divided into three sections: trusted, protected, and unprotected. An authorization mechanism stores and retrieves authorization data from the trusted section of the global data store. A common session manager stores and retrieves data from the protected and unprotected sections of the global data cache. Using the authorization mechanism, software applications may verify that a user is authorized without prompting the user for authorization information. Using the common session manager, software applications may store and retrieve data to and from the global data store, allowing the sharing of data during a user session. After the user session terminates, the data in the global data cache corresponding to the user session is invalidated.

The disclosed embodiments provide a system for processing data. During operation, the system determines, based on data retrieved from a data store in an online system, features related to a user of the online system and an entity. Next, the system applies, to the features, a tree-based model that predicts outcomes between users and entities to generate a set of values representing interactions among the features. The system then inputs the set of values into a machine learning model to produce a score representing a likelihood of an outcome between the user and the entity. Finally, the system outputs a recommendation related to the user and the entity based on the score.
