A cache system is updated upon determining that a current privilege has not been checked for the session. Updating the cache system includes receiving all data items that are accessible for the current privilege. The cache system stores each received data item in association with a privilege set. The privilege set is enabled to include at least one privilege that is granted for the corresponding data item. The current privilege is stored in the privilege set of each data item when the cache system is updated based on the current privilege.
