System and method of dynamic online session caching

A cache engine, comprising:

• a cache memory being allocated to store information of a plurality of users participating in an online communication session, each user being allocated a normal section and an exception section in the cache memory, the normal section storing predictable behavior of the user and the exception section storing unpredictable behavior of the user;
• and
• a normal/exception handler operable to determine whether a user's behavior is predictable or unpredictable and which cached user behavior is to be multicasted to the other users.

A computer-readable medium storing a method comprising:

• determining in a cache memory space a normal section memory size for storing predictable player behavior and an exception section memory size for storing unpredictable player behavior for each player participating in an online gaming session;
• dynamically allocating the cache memory space for each of a plurality of players;
• synchronizing the online gaming session display for all the players by sending information regarding whether a specific player's behavior is predictable or unpredictable, multicasting this information, and retrieving appropriate locally cached player behavior in response to the multicasted information.
