Abstract: Efficiently processing messages at a proxy without intermediary copying increases a proxy's capabilities since fewer resources are expended on operations, such as intermediary copying. A proxy determines which data of a message received into memory will be maintained. The proxy indicates, in an ordered encoding, locations of the determined data and of update data. The update data may be a new message segment, session identifier, etc. The ordered encoding, which indicates the data in order as they will occur in the forwarded message, is used to forward the message with the maintained data and the update data.

Abstract: Determining server capabilities during a discrete time period, or interval, allows for more efficient processing of client requests. Updating a proportional server capability load balancing information encoding at intervals allows a load balancer to handle client requests without the overhead of determining current server capabilities. Decision-making can be reduced to quick selection of one of a group of servers without considering the server's capability, since the server's capability has previously been considered when collecting the load balancing information.

Abstract: Techniques have been developed to encode in an XML schema element an identification of a class that implements the element. Using an XML schema encode in this way, a parser may perform (at parse time) application-specific modifications to an active document object model (DOM) tree. Linking the specification of application-specific processing to the schema provides significant maintenance advantages. Furthermore, the technique allows provision of a scripting facility. Two suitable XML facilities that may be used to encode the extensions are (1) attributes in a name space declared in the schema and (2) annotations. A computer readable encoding of an XML schema element, the encoding including an extension mechanism that identifies a class that implements the element.
