Abstract

Systems, methods, and computer-program products receive a communication request, identify the communication request as a proxy request, generate a fake SID for the communication request, and transmit the proxy request using the generated fake SID.

Claims

1. A computer-implemented method comprising:

receiving a communication request;

identifying the communication request as a proxy request;

generating a fake SID for the communication request; and

transmitting the proxy request using the generated fake SID.

2. The method of claim 1, wherein transmitting the proxy request using the generated fake SID comprises transmitting the proxy request on a same socket as a transmitted tunneling request.

3. The method of claim 1, wherein identifying the communication request as a proxy request comprises:

examining the Uniform Resource Identifier (URI) of the communication request.

4. The method of claim 1, further comprising:

storing the fake SID for the communication request in a session map.

5. The method of claim 1, further comprising:

generating a sequence number for the communication request.

6. The method of claim 5, wherein generating a sequence number for the communication request comprises generating a sequence number for the communication request using an auto-incrementing counter.

7. The method of claim 5, wherein generating a sequence number further comprises incrementing a counter, and using a value of the incremented counter to generate the sequence number.

8. The method of claim 1, further comprising examining the communication request to identify a tunneling command.

9. The method of claim 8, wherein the tunneling command is selected from the group of tunneling commands consisting of a request to open a session, a request to close a session, a request to send over a session, and a request to idle a session.

10. The method of claim 9, further comprising generating a sequence number of zero (0) when the tunneling command is a request to open a session.

11. The method of claim 1, wherein generating a fake SID for the communication request comprises generating a fake SID by looking up the fake SID in a session map.

12. The method of claim 1, wherein transmitting the proxy request comprises transmitting the proxy request to a destination address.

17. The method of claim 5, wherein the communication request comprises a tunneling command.

18. The method of claim 17, wherein the tunneling command is selected from the group of tunneling commands consisting of a request to open a session, a request to close a session, a request to send over a session, and a request to idle a session.

19. The method of claim 1, wherein transmitting the communication request comprises transmitting the communication request to a destination address.

13. A computer-implemented method comprising:

transmitting a communication request, the communication request comprising a proxy request;

receiving a fake SID in response to the communication request, the fake SID generated by a tunneling service;

transmitting the proxy request on the tunneling service using the generated fake SID.

14. The method of claim 13, wherein transmitting the communication request using the generated fake SID comprises transmitting the communication request on a same socket as a transmitted tunneling request.

15. The method of claim 13, further comprising generating a sequence number for the communication request.

16. The method of claim 13, wherein generating a sequence number for the communication request comprises generating a sequence number for the communication based on an auto-incrementing counter.

20. A system, comprising:

a computing device; and

a tunneling service operable to interact with the computing device and operable to perform operations comprising;

receiving a communication request from the computing device;

identifying the communication request as a proxy request;

generating a fake SID for the communication request;

transmitting the proxy request using the generated fake SID.

21. The system of claim 20, wherein transmitting the proxy request using the generated fake SID comprises transmitting the proxy request on a same socket as a transmitted tunneling request.

22. The system of claim 20, wherein identifying the communication request as a proxy request comprises:

examining the Uniform Resource Identifier (URI) of the communication request.

23. The system of claim 20, wherein the tunneling service is further operable to perform operations comprising:

storing the fake SID for the communication request in a session map.

24. The system of claim 20, wherein the tunneling service is further operable to perform operations comprising:

generating a sequence number for the communication request.

25. The system of claim 24, wherein generating a sequence number for the communication request comprises generating a sequence number for the communication request using an auto-incrementing counter.

26. The system of claim 24, wherein generating a sequence number further comprises incrementing a counter, and using a value of the incremented counter to generate the sequence number.

27. The system of claim 20, wherein the tunneling service is further operable to perform operations comprising:

examining the communication request to identify a tunneling command.

28. The system of claim 27, wherein the tunneling command is selected from the group of tunneling commands consisting of a request to open a session, a request to close a session, a request to send over a session, and a request to idle a session.

29. The system of claim 28, wherein the tunneling service is further operable to perform operations comprising generating a sequence number of zero (0) when the tunneling command is a request to open a session.

30. The system of claim 20, wherein generating a fake SID for the communication request comprises generating a fake SID by looking up the fake SID in a session map.

31. The system of claim 20, wherein transmitting the proxy request comprises transmitting the proxy request to a destination address.

32. A computer program product, encoded on a computer-readable medium, operable to cause a data processing apparatus to perform operations comprising:

receiving a communication request;

identifying the communication request as a proxy request;

generating a fake SID for the communication request; and

transmitting the proxy request using the generated fake SID.

33. The computer program product of claim 32, wherein transmitting the proxy request using the generated fake SID comprises transmitting the proxy request on a same socket as a transmitted tunneling request.
