Abstract

A local proxy system includes a storage device having a local proxy and a physical port connection. The local proxy is part of a split proxy configuration having a local proxy and a remote proxy. The physical port connection is operative to receive commands from a host via an internet application protocol; and to transmit commands to the host via a modem control protocol, to thereby function as a gateway for conveying these commands to a remote proxy, via the host. Also provided is a method of optimizing communication over a network; and a local proxy system that includes a storage device having a local proxy. The storage device is in connection with a host via a physical port connection complying with a standard storage device interface.

Claims

1. A method of optimizing communication over a network, the method comprising:

receiving a first set of commands from a host via an internet application protocol, the receiving being performed by a local proxy running on a storage device, the local proxy being part of a split proxy configuration having a local proxy and a remote proxy; and

transmitting a second set of commands from the local proxy to the host via a modem control protocol, to thereby convey the second set of commands to the remote proxy, via the host,

wherein connection between the storage device and the host is a physical port connection.

2. The method of claim 1, further comprising enabling a logical connection between the local proxy and the remote proxy via a host functioning as a modem, the remote proxy being part of the split proxy configuration and being in communication link to a web server via a network.

3. The method of claim 2, wherein, with the remote proxy being in communication link to a web server via a network, the local proxy is in communication link to the web server via the remote proxy.

4. The method of claim 2, further comprising authenticating the remote proxy, the authenticating being performed by the local proxy via the host.

5. The method of claim 1, wherein the internet application protocol includes any type of client-server protocol, one such client-server protocol being HTTP protocol.

6. The method of claim 1, wherein the physical port connection complying with a standard storage device interface.

7. The method of claim 1, servicing the first set of commands with the second set of commands, the servicing being performed by the local proxy via the modem control protocol.

8. A local proxy system comprising:

a storage device including;

a) a local proxy that is operative to run on storage device, the local proxy being part of a split proxy configuration having a local proxy and a remote proxy;

b) a physical port connection operative to support a first logical protocol and a second logical protocol, the first logical protocol being used for receiving a first set of commands from a host via an internet application protocol, and the second logical protocol being used for transmitting a second set of commands to the host via a modem control protocol, to thereby function as a gateway for conveying the second set of commands to the remote proxy, via the host.

9. The local proxy system of claim 8, wherein the first logical protocol and the second logical protocol are a same logical protocol.

10. The local proxy system of claim 8, wherein the storage device is a removable storage device.

11. The local proxy system of claim 8, wherein the internet application protocol includes a client-server protocol, one such client-server protocol being HTTP protocol.

12. The local proxy system of claim 8, wherein the storage device complies with any memory card format, including any one of a secure digital (SD) memory card format, a multimedia card (MMC) format and a compact flash (CF) memory card format.

13. The local proxy system of claim 8, wherein, with the remote proxy being in communication link to a web server via a network, the local proxy is in communication link to the web server via the remote proxy, and wherein the host functions as a modem to enable a logical connection between the local proxy and the remote proxy.

14. The local proxy system of claim 8, wherein the host is compatible with a mobile handset device.

15. The local proxy system of claim 8, wherein the local proxy authenticates the remote proxy via the host.

16. The local proxy system of claim 8, wherein the local proxy services the first set of commands with the second set of commands via the modem control protocol.

17. A local proxy system comprising:

a storage device including;

a) a local proxy that is operative to run on the storage device, the local proxy being part of a split proxy configuration having a local proxy and a remote proxy;

b) a physical port connection operative to provide a first communication link via a first logical protocol and a second communication link via a second logical protocol, the first logical protocol being used for receiving commands from a host, and

wherein the second logical protocol being used for receiving commands to the host, to thereby function as a gateway for conveying the second set of commands to the remote proxy, via the host,

wherein the physical port connection complies with a standard storage device interface.

18. The local proxy system of claim 17, wherein the first logical protocol and the second logical protocol are a same logical protocol.

19. The local proxy system of claim 17, wherein the first communication link and the second communication link are a single communication link.

20. The local proxy system of claim 17, wherein the storage device is a removable storage device.

21. The local proxy system of claim 17, wherein the storage device complies with any memory card format, including a secure digital (SD) memory card format, a multi memory card (MMC) memory card format and a compact flash (CF) memory card format.

22. The local proxy system of claim 17, wherein, with the remote proxy being in communication link to a web server via a network, the local proxy is in communication link to the web server via the remote proxy, and wherein the host functions as a modem to enable a logical connection between the local proxy and the remote proxy.

23. The local proxy system of claim 17, wherein the host is compatible with a mobile handset device.

24. The local proxy system of claim 17, wherein the local proxy authenticates the remote proxy via the host.

25. The local proxy system of claim 17, wherein the local proxy services the first set of commands with the second set of commands via the modem control protocol.
