Abstract: In a networked computer system, partitioned proxies are defined that each include a cache of connection information that allows for quickly routing a remote invocation to an object without suffering the overhead of determining routing information for the object each time the object is remotely invoked. Multiple copies of an object are created in multiple computer systems. A partitioned proxy is then created that points to each copy of the object. The partitioned proxies allow quickly accessing these object copies without the overhead of synchronizing their state data. Caching connection information within the partitioned proxies allows a computer system to invoke a remote object without the performance penalty of determining with each invocation the connection information for accessing the remote object.

Abstract: A method, apparatus, system, and signal-bearing medium that, in an embodiment, switch between synchronous processing and asynchronous processing for a request if the synchronous processing for the request is unsuccessful and send a synchronous response to a client that initiated the request after the asynchronous processing of the request. In an embodiment, an asynchronous response for the asynchronous processing is sent to a bridge, which then sends the synchronous response to the client. In this way, the client may receive a synchronous response even if the request is performed by asynchronous processing.
