Abstract
A method and system for providing state-full access to files and resuming access should a connection be broken. A resume key is returned to the client that allows the client to request a duplicate handle to an open file. The duplicate handle can be used to access the file in the same manner as the handle used to open the file. When a connection is broken, the file remains open on the server for a period of time and the state information associated with the file is maintained. Even if a connection is not broken, a client may request one or more duplicate handles and establish other channels (also known as connections) with which to access the file.
