Abstract: A system for providing indications of documents currently opened by members of a group, in which document open and close operations are detected, and conveyed to a server system. The server system receives the document operation messages, and uses them to maintain lists of open documents associated with individual users through records in a user database that also indicate individual users' on-line status. When the server system transmits the on-line status of a user to other users that have an interest in that user (e.g. fellow members of a collaboration team, development project or the like, or user's having entered that user in their buddy list, etc.), an open documents list for that user is included in the message along with his or her on-line status information. The client systems maintain lists of currently accessing users for open documents they have received identifiers of within open documents lists contained in such on-line status messages.

Abstract: Systems, methods and computer products for throttling client access to servers. Exemplary embodiments include a method to throttle client access to servers, the method including maintaining local state information on active and pending requests, receiving a delay call from a client, calculating a delay, incrementing a pending operation count, p, returning the delay value to the client, decrementing the pending operation count, p, and incrementing an active operation count, a, in response to a start of an operation by a client, decrementing the active operation count in response to a operation finishing, recording a timestamp to record when a last pending operation should start, and resetting the pending operation count to 0, in response to a next delay request being received after the timestamp is recorded.
