Abstract
A method and apparatus for managing session information. In one embodiment, a communication session is established between a client computer and a server computer. When the client computer and the server computer establish the communication session, the client or the server typically stores information about the communication session, which is referred to as 'session information.' The session information is stored in a first log file stored in a persistent volatile memory and in a cache file stored in a volatile memory of the server. The cache file is reconstructed after a server failure by retrieving the session information stored in the first log file.
