System and method for event notification through a firewall

摘要

A system for providing client callbacks includes a client having a client application and a client firewall operable to block a client callback to the client application from a server. The server includes a server firewall and a server workspace. The server workspace has data protected by the server firewall and a permissibility framework associating a predefined type of the data with the client application. The server workspace is operable to generate a client callback for the client application in response to the presence of the predefined data type. A server-side proxy is operable to provide the client application access to the server workspace through the server firewall. The client application is operable to connect to the server workspace via the server-side proxy to receive the client callback.
