An application server includes an asynchronous event manager configured for selectively terminating an instance executing a messaging session, based on detecting a message from a gateway server that the incoming call is a call having a type that differs from the prescribed type intended for the messaging session. The asynchronous event manager terminates the instance by setting global variables accessible by the instance that specify that the call is rejected (i.e., the connection between the gateway and the instance executing the messaging session is terminated) due to the incoming call being of a different type than intended for that messaging session, for example the call being a fax call instead of a voice call. The instance executing the messaging session checks the global variables prior to committing to execution of critical operations that affect stored subscriber messaging data, for example before sending a recorded message for storage, or changing a state of a stored message from a new message to a stored message or deleted message. If the global variables indicate that the messaging session should be terminated, the instance rolls back the necessary data structures by deleting any necessary data (e.g., log entries, application state information, recorded messages, etc.), and terminates the instance.

An application server generates and maintains a server-side data record, also referred to as a 'brownie', that includes application state information and user attribute information for multiple users within a single session controlled by a web-based browser. The brownie includes a session identifier that uniquely identifies the session, and a subsession identifier that uniquely identifies each corresponding user of the application session. As each new user is added to the session, for example by initiating a call to the new user, the application server stores the subsession identifier and corresponding application state information for the new user in the same brownie. In response to receiving a second web page request from the browser that includes the session identifier, the application server initiates a new web application instance, and recovers the brownie from the memory based on the session identifier included in the second page request.

An executable process, configured for storing and retrieving data from a storage medium having a prescribed storage definition, is configured for converting an array having a prescribed data structure into a string having array descriptors that specify the prescribed data structure. The array descriptors are used to identify for each a element its corresponding element name and element value. The array descriptors also identify for each element its relative depth within the array, for example whether a given array element is a subelement of another array element. Hence, the array can be stored and recovered from the storage medium without modification of the prescribed storage definition and without loss of the data structure of the array.
