Abstract
A system and method for maintaining application state information in a stateless environment. State data of arbitrary length is stored in a storage area at a location referenced by a storage handle. The storage handle is recorded by the application and is used to reaccess the data as required. The storage handle is defined as a short fixed length field enabling compact reference and use regardless of the amount of data stored. Storage space is periodically reclaimed and reused after being freed by the application.
