Abstract

A system for dynamically controlling a network device is implemented in a network device including a parser and a service provider. The parser includes instructions for selectively invoking the service provider in response to a command parsed from an external input received by the network device.

Claims

1. A dynamically-controllable network proxy comprising a parser module and a service provider module coupled to said parser module, said parser module including instructions for selectively invoking said service provider module in response to a command parsed from an external input received by said network proxy, said service provider module comprising instructions for performing a predetermined function at said network proxy.

2. The network proxy of claim 1, wherein said network proxy is arranged between a client and a server, said parser module further including instructions for selectively invoking said service provider module in response to a command parsed from a data object received from the server.

3. The network proxy of claim 2, wherein said service provider module comprises instructions for transcoding said data object prior to forwarding said data object to the client.

4. The network proxy of claim 1, wherein said service provider module comprises instructions for reconfiguring said network proxy.

5. The network proxy of claim 4, wherein said service provider module further comprises instructions for setting an operational parameter of said network proxy.

6. The network proxy of claim 1, wherein the external input comprises an HTTP-compliant message.

7. The network proxy of claim 1, wherein said network proxy is arranged between a client and a server, said parser module further including instructions for selectively invoking said service provider module in response to a command parsed from a request received from the client.

8. The network proxy of claim 1, wherein said network proxy is arranged between a client and a remote network device, said parser module further including instructions for selectively invoking said service provider module in response to a command parsed from a data object received by said network proxy from the remote network device.

9. The network proxy of claim 1, wherein said service provider module further comprises instructions for managing a log file used by said network proxy.

10. The network proxy of claim 1, wherein said service provider module further comprises instructions for obtaining status information from said network proxy.

11. The network proxy of claim 1, wherein said service provider module further comprises instructions for restarting said network proxy.
