Token caching in trust chain processing

A computer usable program product comprising a computer usable medium including computer usable code for token caching in a trust chain processing, the computer usable code comprising:

• computer usable code for mapping an information in a token associated with a first request, forming mapped information;
• computer usable code for determining whether a requester of the first request has provided a constraint in the first request, the constraint concerning the token, the constraint forming a client constraint;
• computer usable code for storing the client constraint;
• computer usable code for storing the information and the mapped information, forming stored information;
• computer usable code for receiving the token in a second request;
• computer usable code for reusing the stored information if the client constraint allows reusing the stored information;
• computer usable code for determining whether a target system receiving the mapped information has provided a second constraint, the second constraint concerning the mapped information, the second constraint forming a server constraint;
• computer usable code for reusing the stored information if the server constraint allows reusing the stored information;
• and
• computer usable code for resolving a conflict between the client constraint and the server constraint with respect to the token and the mapped information resulting from the token.

A data processing system for token caching in a trust chain processing, the data processing system comprising:

• a storage device including a storage medium, wherein the storage device stores computer usable program code;
• and
• a processor, wherein the processor executes the computer usable program code, and wherein the computer usable program code comprises:
• computer usable code for mapping an information in a token associated with a first request, forming mapped information;
• computer usable code for determining whether a requester of the first request has provided a constraint in the first request, the constraint concerning the token, the constraint forming a client constraint;
• computer usable code for storing the client constraint;
• computer usable code for storing the information and the mapped information, forming stored information;
• computer usable code for receiving the token in a second request;
• and
• computer usable code for reusing the stored information if the client constraint allows reusing the stored information.
