State management of server-side control objects

摘要

The state of one or more server-side control objects is managed using a transportable state structure that is communicated between a web server and a client. The transportable state structure may include state information, hierarchical information, and an integrity code. The state information is related to properties of the server-side control objects. The hierarchical information is used by the server to locate an appropriate server-side control object in the hierarchy into which associated state information is to be loaded. The integrity code allows the server to determine whether the transportable state structure was corrupted during the roundtrip between the server and the client. Prior to a response to the client, the state information of one or more server-side control objects is recorded into the transportable state structure for transmission to the client in the response. The transportable state structure is then returned to the server and loaded into the server-side control objects to restore the hierarchy to its previous state.
