Abstract: An exemplary embodiment of the present invention is a method for transmitting compacted text data. A standard form data message is translated into a compacted form data message. The translating includes first locating a long tag in the standard form data message. A short tag in a sender translation table that corresponds to the long tag is identified in a sender translation table. The compacted form data message is created by substituting the short tag for the long tag in the standard form data message. The compacted form data message is transmitted to a receiver system. Then, a flag is set in response to determining if the sender translation table needs to be transmitted to the receiver system and the flag is transmitted to the receiver system. The sender translation table is transmitted to the receiver system in response to the determination of whether the translation table needs to be transmitted. Additional embodiments include a system and storage medium for transmitting compacted text data.

Abstract: A method, a system, and a computer program product implements traffic shaping by processing as a synchronous request, tasks representing one or more units of work contained within the request. Before a request is sent through the network, the request is inspected in order to derive the amount of work that the request would generate in the network. A traffic manager queries the amount of work in that request compared to the amount of work that the network can support and generates a number of traffic envelopes. Based on the results of this query, “task pruning” may be implemented to break the request into smaller manageable task that fit into the traffic envelopes. Task pruning may also enable only a subset of the work to be performed. Thus, a measure of the amount of work, rather than the amount of data, within a request is considered when scheduling the request.

Abstract: A secure communication protocol (e.g., SSL) transaction request from a client to a server is intercepted at a client-side proxy communicatively coupled to the client and logically deployed between the client and the server.

This enables the server-side proxy to engage in secure communications with the server in a transparent fashion.
