A method is described for a computing system with multiple virtual machines that does not support persistence of session information in a shared memory that is internal to the computing system and that is accessible to each of the virtual machines. The method involves receiving a deployment descriptor that specifies a persistence scope that does not extend beyond the computing system. Then, as a consequence of the receiving, a plug-in is instantiated for the computing system's file system. The, over the course of a session, managing the persistence of the session's session state information in the computing system's file system by, with program code provided by the plug-in, translating a first command that is not specific to the file system into a second command that is specific to the file system. The session state information comprises a plurality of attributes. The command causes a process to be performed The process is selected from the group consisting of: storing in the file system one of the attributes; and, retrieving from the file system one of the attributes.
