Abstract

A method of facilitating, via an embedded local server, dynamic responses to requests originating from an application and directed to a server is disclosed. An intermediary intercepts requests responds to the requests with locally stored data. The intermediary may also forward requests to an embedded local server for processing based on local data.

Claims

1. A computer-implemented method, comprising:

intercepting, at an intermediary, from an application running on a first computing device, a first request;

wherein the first request is a request directed to a server, and includes;

a first resource identifier; and

one or more first protocol methods, wherein the one or more first protocol methods represent actions that may be performed on a resource in conformance to a particular protocol;

matching the first resource identifier and the one or more first protocol methods with an interception key in an interception key registry, wherein the interception key comprises a second resource identifier and one or more references to second protocol methods;

based at least in part on the interception key, relaying the first request to an embedded server;

receiving, from the embedded server, a response to the first request;

wherein the method is performed by one or more computing devices.

2. The method of claim 1, further comprising:

determining an embedded server based on the interception key;

wherein determining the embedded server comprises matching the key to an embedded server address from a plurality of embedded server addresses stored in an embedded server registry.

3. The method of claim 1, wherein at least one of the one or more of the first or second protocol methods are implied by a NULL value reference.

4. The method of claim 3, wherein:

the first request is a request to retrieve or store data; and

the resource identifier indicates the data to be stored or retrieved.

5. The method of claim 4, further comprising:

the embedded server storing data in an embedded database;

receiving a second request, wherein the second request is a request to retrieve data from the server;

the embedded server responding to the second request using data stored in the embedded database;

subsequent to storing data in the embedded database, synchronizing the embedded database with the server.

6. The method of claim 5, wherein the step of synchronizing the embedded database with the server comprises determining that synchronization should occur, based, at least in part, on one or more policy criteria.

7. The method of claim 6, wherein the policy criteria includes criteria related to one or more of:

time;

power consumption;

communication privacy;

network usage cost;

network availability;

conflicts caused by server contention;

or

user expressed preferences.

8. The method of claim 1, further comprising:

determining that the first request should be sent to the embedded server based at least in part on one or more policy criteria.

9. The method of claim 8, wherein the policy criteria includes criteria related to one or more of:

time;

power consumption;

communication privacy;

network usage cost;

network availability;

conflicts caused by server contention;

or

user expressed preferences.

10. The method of claim 1, wherein the first computing device is a mobile computing device.

11. The method of claim 1, wherein the intermediary is a browser plugin.

12. The method of claim 1, further comprising:

storing, at an authorization registry, an authorization key, wherein the authorization key represents an authorization condition associated with the interception key;

wherein the response to the first request is based, at least in part, on whether or not the authorization condition has been satisfied.

13. The method of claim 12, further comprising:

based on a determination that the authorization condition is no longer satisfied;

removing the authorization key from the authorization registry; and

removing the interception key from the interception key registry.

14. The method of claim 1, further comprising:

the embedded server revising the interception key registry, wherein the step of revising the embedded server registry comprises at least one of the following;

changing a key in the interception key registry;

adding a key to the interception key registry; and

removing a key from the interception key registry.

15. A computer-implemented method, comprising:

intercepting, at an intermediary, from an application running on a first computing device, a first request;

wherein the first request is a request directed to a server, and includes;

a first resource identifier; and

one or more first protocol methods, wherein the one or more first protocol methods represent actions that may be performed on a resource in conformance to a particular protocol;

matching the first resource identifier and the one or more first protocol methods with an interception key in an interception key registry, wherein the interception key comprises a second resource identifier and one or more references to second protocol methods;

relaying the first request to the server;

receiving, from the server, a first response to the first request;

based at least in part on the interception key, relaying the first response to an embedded server;

the embedded server, based on a determination made from analyzing the first response, instructing the intermediary to store first data associated with the first response;

wherein the method is performed by one or more computing devices.

16. The method of claim 15, further comprising:

intercepting, at an intermediary, a second request, wherein the second request is directed to the server and includes the first resource identifier;

based at least in part on the interception key, the intermediary determining that the request can be satisfied with the first data;

the intermediary responding to the second request using first data.

17. The method of claim 15, further comprising:

determining that the first request should be relayed to the embedded server based at least in part on one or more policy criteria.

18. The method of claim 17, wherein the policy criteria includes criteria related to one or more of:

time;

power consumption;

communication privacy;

network usage cost;

network availability;

conflicts caused by server contention;

or

user expressed preferences.

19. The method of claim 15, further comprising:

the embedded server revising the interception key registry, wherein the step of revising the embedded server registry comprises at least one of the following;

changing a key in the interception key registry;

adding a key to the interception key registry; and

removing a key from the interception key registry.
