Abstract: Enhanced client-server communication in a cached communication environment is described. A server computer executes a server application. The server application requests a server communication application to generate a server object. The server object is independent from a client object that is modified to communicate client data. The server object is associated with a server object identifier. The server application receives a copy of the client object from the server communication application. The copy of the client object is associated with a client object identifier. The server application determines whether the server object identifier has an expected relationship with the client object identifier. The server application applies a disposition rule to data referenced in the copy of the client object if the server object identifier has the expected relationship with the client object identifier.

Abstract: A method and apparatus for creating a catalog for use with at least one computer system that manages a plurality of email messages. The catalog provides an index into the plurality of email messages, and comprises a plurality of display identifiers that each identifies an entity. The catalog correlates at least some of the plurality of display identifiers to corresponding email addresses. The method comprises creating the catalog to include a user interface that enables the display identifiers to be displayed to a user and that enables the catalog to be searched based upon at least some information other than the display identifiers.

Abstract: A method and apparatus for creating a catalog for use with at least one computer system that manages a plurality of email messages. The catalog provides an index into the plurality of email messages, and comprises a plurality of identifiers that each identifies an entity. The catalog also correlates at least some of the plurality of identifiers to corresponding email addresses. The method for creating a catalog comprises creating the catalog to include information defining a temporal interval during which at least one email address corresponds to a first entity.

Abstract: A method and apparatus for use in a computer system comprising an email system that generates and receives email messages. The email system manages a first plurality of email messages comprising at least some of the email messages generated and received by the email system. The email system also has a global address catalog that comprises information and provides an index into the first plurality of email messages. The computer system further comprises an extension system that interfaces with the email system and manages a second plurality of email messages comprising at least some of the email messages generated and received by the email system. The method comprises creating an extender catalog, for indexing into the second plurality of email messages, that comprises at least some information that is different than the information in the global address catalog.
