Abstract

A method for anonymous subject-based addressing includes receiving, from a client computer, a point-to-point request message. The method also includes converting the point-to-point request message to a subject-based message. The subject-based message is also multicast. Additionally, a response is received to the subject-based message. The method also includes converting the response to the subject-based message to a point-to-point response message. Moreover, the point-to-point response message is transmitted back to the client computer.

receiving a response to the subject-based message, the response to the subject-based message addressed with a subject-based addressing protocol;

converting the response to the subject-based message to a point-to-point response message; and

transmitting the point-to-point response message back to the client computer.

2. The method of claim 1, wherein the converting includes assigning a subject name and a reply subject to the subject-based message.

3. The method of claim 2, wherein the subject-based message is delivered to a group of subscribers that have subscribed to receive subject-based messages which have been assigned the subject name.

4. The method of claim 3, wherein the group of subscribers that have subscribed to receive the subject-based message can dynamically change.

5. The method of claim 1, wherein the point-to-point request message is based on HyperText Transfer Protocol.

6. The method of claim 1, wherein the subject-based message is independent of an identity of a recipient.

7. The method of claim 1, wherein the subject-based message is independent of a protocol used by a recipient of the subject-based message.

8. A method for processing a point-to-point request based on HyperText Transfer Protocol (HTTP), the method comprising:

receiving, from a client computer, the point-to-point request;

converting the point-to-point request to a subject-based message, the subject-based message addressed with a subject-based addressing protocol;

multicasting the subject-based message to a number of application servers across a network;

receiving a response to the subject-based message from one of the number of application servers, the response to the subject-based message addressed with a subject-based addressing protocol;

extracting content from the response to the subject-based message;

generating a point-to-point response using the content from the response to the subject-based message; and

sending the point-to-point response back to the client computer.

9. The method of claim 8, wherein the converting includes assigning a subject name and a reply subject to the subject-based message.

10. The method of claim 8, wherein the subject-based message is independent of an identity of a recipient.

11. The method of claim 8, wherein the subject-based message is independent of a protocol used by a recipient of the subject-based message.

12. The method of claim 8, wherein the subject-based message is delivered to a group of subscribers that have subscribed to receive subject-based messages which have been assigned the subject name.

13. The method of claim 12, wherein the group of subscribers that have subscribed to receive the subject-based message can dynamically change.

14. A machine-readable medium that provides instructions, which when executed by a processor, cause said processor to perform operations comprising:

receiving, from a client computer, a point-to-point request message;

converting the point-to-point request message to a subject-based message, the subject-based message addressed with a subject-based addressing protocol;

multicasting the subject-based message;

receiving a response to the subject-based message, the response to the subject-based message addressed with a subject-based addressing protocol;

converting the response to the subject-based message to a point-to-point response message; and

transmitting the point-to-point response message back to the client computer.

15. The machine-readable medium of claim 14, wherein the converting includes assigning a subject name and a reply subject to the subject-based message.

16. The machine-readable medium of claim 14, wherein the point-to-point request message is based on HyperText Transfer Protocol.

17. The machine-readable medium of claim 14, wherein the subject-based message is independent of an identity of a recipient.

18. The machine-readable medium of claim 14, wherein the subject-based message is independent of a protocol used by a recipient of the subject-based message.

19. The machine-readable medium of claim 14, wherein the subject-based message is delivered to a group of subscribers that have subscribed to receive subject-based messages which have been assigned with the subject name.

20. The machine-readable medium of claim 19, wherein the group of subscribers to receive the subject-based message can dynamically change.

21. A machine-readable medium that provides instructions for processing a point-to-point request based on HyperText Transfer Protocol (HTTP), which when executed by a processor, cause said processor to perform operations comprising:

receiving, from a client computer, the point-to-point request;

converting the point-to-point request to a subject-based message, the subject-based message addressed with a subject-based addressing protocol;

multicasting the subject-based message to a number of application servers across a network;

receiving a response to the subject-based message from one of the number of application servers, the response to the subject-based message addressed with a subject-based addressing protocol;

extracting content from the response;

generating a point-to-point response using the content from the response; and

sending the point-to-point response back to the client computer.

22. The machine-readable medium of claim 21, wherein the converting includes assigning a subject name and a reply subject to the subject-based message.

23. The machine-readable medium of claim 21, wherein the subject-based message is independent of an identity of a recipient.

24. The machine-readable medium of claim 21, wherein the subject-based message is independent of a protocol used by a recipient of the subject-based message.

25. The machine-readable medium of claim 21, wherein the subject-based message is delivered to a group of subscribers that have subscribed to receive subject-based messages which have been assigned with the subject name.

26. The machine-readable medium of claim 25, wherein the group of subscribers to receive the subject-based message can dynamically change.

27. An application server coupled to a network, the application server comprising:

a database having data;

a processor coupled to the database, the processor to process subject-based messages received from a server, the subject-based messages addressed with a subject-based addressing protocol and including requests for data content wherein the subject-based messages are generated from point-to-point messages received from a client computer, the processing including;

listening for a subject-based request message being received from the network;
