Abstract

Methods and apparatus for dynamic content customization provided to clients. When a profile repository is used to store profiles indicating typical device characteristics for various clients, the repository is configured to allow a stored profile to be flagged to indicate a client is capable of being queried for dynamically determined changes and/or additions to its stored profile. Communication between content providers, e.g., one or more servers, and the client may be configured so a minimum number of notifications need be made by the client to the servers to indicate the client can be queried for specific dynamic characteristics or deviations from a default profile (if any).

Claims

1. A method for a client, comprising:

first requesting a first content from a content provider;

providing a characteristic profile to the content provider indicating characteristics of the client;

receiving a first reply from the content provider responsive to the first requesting, the first reply including a query for a characteristic of the client;

second requesting the first content from the content provider, the second requesting incorporating a query result for the query; and

receiving a second reply from the content provider responsive to the second requesting, the second reply including the first content or portion thereof, wherein the first content or portion thereof is determined based at least in part on the characteristic.

2. The method of claim 1, further comprising:

third requesting a second content from the content provider, wherein the third requesting automatically incorporates the query result for the query.

3. The method of claim 1, wherein for content that is arranged in a hierarchical structure, the method further comprising:

determining if the content provider wants the query result to be automatically incorporated into a third requesting of second content from the content provider that is lower in the hierarchical structure than the first content.

4. The method of claim 3, further comprising:

determining if the content provider is caching the query result, and if so, determining if the query result has changed since the first requesting; and

wherein if the query result has not changed, said third request does not incorporate the query result for the query.

5. The method of claim 4, wherein if the query result has changed, said third request automatically incorporates the query result for the query.

6. The method of claim 2, further comprising:

determining if the content provider is caching the query result, and if so, determining if the query result has changed since the first requesting; and

wherein if the query result has not changed, said third request does not incorporate the query result for the query, and wherein if the query result has changed, said third request automatically incorporates the query result for the query.

7. The method of claim 1, further comprising:

storing the query result in a HyperText Transport Protocol (HTTP) request header provided to the content provider.

8. The method of claim 1, wherein the query is received in a HyperText Transport Protocol (HTTP) response header provided by the content provider.

9. The method of claim 1, wherein requesting the content and receiving the first reply is performed according to the Composite Capability/Preference Profiles (CC/PP) protocol.

10. The method of claim 1, wherein the characteristic profile includes an entry indicating whether the client can be queried for an operational characteristic.

11. The method of claim 10, wherein the characteristic profile is formatted as a UAProf profile.

12. The method of claim 1, wherein the first reply comprises a selected one of the content or a frame-set for the content.

13. The method of claim 1, wherein the characteristic is a selected one of processor type, processor speed, processor mode, available memory, available storage, or available network connectivity.

14. The method of claim 1, wherein the characteristic is a selected one of availability of:

peer clients, a camera, a microphone, a text to speech converter, a speech to text converter, a soft radio, a graphics processor.

15. The method of claim 1, wherein the characteristic is availability of an encryption processor.

16. A method, comprising:

receiving from a client a first request for first content and a characteristic profile indicating characteristics of the client;

providing a first response to the client lacking all of the requested first content, but wherein the first response incorporates a query for a characteristic of the client;

receiving a second request for the first content, wherein the second request incorporates a query result for the query; and

providing the first content to the client in accord with the query result.

17. The method of claim 16, further comprising:

wherein the characteristic profile indicates the client may be queried for characteristics not identified in the characteristic profile;

18. The method of claim 16, wherein the characteristic reflects an operational characteristic of the client.

19. The method of claim 18, wherein the operational characteristic is a real-time attribute which changes while the client is operating.

20. The method of claim 18, wherein the operational characteristic is a selected one of available power, available memory, processor type or processor speed.

21. The method of claim 16, further comprising:

issuing a set-cookie command to the client to associate at least the first content with a cookie, wherein the cookie indicates the query result will be cached for all content associated with the cookie.

22. A system comprising:

a content provider communicatively coupled with a client;

wherein the content provider is operative to perform receiving from the client a first request for content, determining the client may be queried for characteristics, providing a response to the client incorporating a query for a characteristic of the client, receiving a second request for the first content incorporating a query result for the query, and providing the first content to the client in accord with the query result; and

wherein the client is operative to perform parsing the response to determine the query, determining the query result, and providing the query result to the content provider in at least a second request for content.

23. The system of claim 22, wherein the client and content provider utilize HTTP to exchange data in accord with the CC/PP protocol.

24. A system comprising:

a proxy for managing communication with a content provider, the proxy operable to parse data received from a content provider to determine a query for a characteristic of the system, and to provide a query result to the content provider incorporating the characteristic of the system;

at least one agent for inspecting the system for various characteristics of the system; and

a manager having an interface communicatively coupled with the proxy to allow the proxy to direct the manger to dynamically instantiate an agent to determine the query result responsive to the query.

25. The system of claim 24, the system further comprising a memory for storing directives for at least the manager, the directives including:

a first directive to store a copy of a default characteristic profile for the system into the memory;

a second directive to identify an entry in the copy for which the agent is required to determine a value;

a third directive to dynamically load the agent to determine the value;

a fourth directive to store the value in the copy of the default characteristics profile.

26. An article comprising a machine-accessible media having associated data, wherein the data, when accessed, results in a machine performing:

first requesting a first content from a content provider;

providing a characteristic profile to the content provider indicating characteristics of the client;

receiving a first reply from the content provider responsive to the first requesting, the first reply including a query for a characteristic of the client;

second requesting the first content from the content provider, the second requesting incorporating a query result for the query; and

receiving a second reply from the content provider responsive to the second requesting, the second reply including the first content, wherein the first content is determined based at least in part on the characteristic.

27. The article of claim 26 wherein the machine-accessible media further includes data, when accessed, results in the machine performing:

determining the content is arranged in a hierarchical structure; and

determining if the content provider wants the query result to be automatically incorporated into a third requesting of second content from the content provider that is lower in the hierarchical structure than the first content.

28. An article comprising a machine-accessible media having associated data, wherein the data, when accessed, results in a machine performing:

receiving from a client a first request for first content and a characteristic profile indicating characteristics of the client;

determining the client may be queried for characteristics not identified in the characteristic profile;

providing a first response to the client lacking all of the requested first content, but wherein the first response incorporates a query for a characteristic of the client;

receiving a second request for the first content, wherein the second request incorporates a query result for the query; and

providing the first content to the client in accord with the query result.

29. The article of claim 28 wherein the machine-accessible media further includes data, when accessed, results in the machine performing:

issuing a set-cookie command to the client to associate at least the first content with a cookie, wherein the cookie indicates the query result will be cached for all content associated with the cookie.
