Abstract

A system, apparatus, and method for improving the user experience when accessing web pages containing embedded objects over a network. In one embodiment, information regarding the contents of a locally accessible cache is added to a request directed to a web server. The information is used to control certain aspects of a pre-fetch process that is designed to reduce network latency affects and improve network resource utilization, thereby improving a user'"'"'s experience. The cache contents information may be provided to an intermediate server via a modification to an existing request-response protocol, with the information being encoded or compressed if desired to reduce data transport requirements. The information is used by the intermediate server to determine whether to request an embedded object referenced in the requested resource or web page, and to determine if a browser having access to the cache will request the object or access the object from the local cache.

Claims

1. A method of optimizing a servicing of a request from an application for a resource, comprising:

forming a request by the application for a resource;

determining a contents of a storage medium accessible by the application;

modifying the request to include information regarding the contents of the storage medium;

communicating the request to a network node;

intercepting the communicated request at an intermediate node;

storing the information regarding the contents of the storage medium at the intermediate node;

forwarding the request to the network node;

receiving a response to the request at the intermediate node;

processing the response to identify one or more embedded objects referenced in the response;

identifying one or more embedded objects referenced in the response that are not contained in the storage medium accessible by the application;

requesting from the network node, without further user intervention, the one or more objects referenced in the response that are not contained in the storage medium accessible by the application;

receiving the one or more objects referenced in the response that are not contained in the storage medium accessible by the application;

wherein, in response to a request from the application for an embedded object referenced in the response, the application accesses the storage medium if the requested object is contained in the storage medium and the application accesses the received one or more objects referenced in the response that are not contained in the storage medium if the requested object is not contained in the storage medium.

2. The method of claim 1, wherein the application is a browser and the storage medium accessible by the application is a local cache.

3. The method of claim 1, wherein modifying the request to include information regarding the contents of the storage medium further comprises modifying an element of a protocol used to control communication of the request.

5. The method of claim 1, wherein determining the contents of the storage medium accessible by the application further comprises encoding data regarding the contents of the storage medium.

6. The method of claim 5, wherein encoding data regarding the contents of the storage medium further comprises performing a hash code on a reference for the contents of the storage medium.

7. The method of claim 1, wherein storing the information regarding the contents of the storage medium at the intermediate node further comprises storing the information until each of the one or more embedded objects referenced in the response has been provided to the application.

8. The method of claim 1, wherein

modifying the request to include information regarding the contents of the storage medium further comprises modifying the request to include an identification of an object and an indication of a date or version of the object;

identifying one or more embedded objects referenced in the response that are not contained in the storage medium accessible by the application further comprises identifying one or more embedded objects referenced in the response that are either not contained in the storage medium accessible by the application or are contained in the storage medium but are stale;

requesting from the network node, without further user intervention, the one or more objects referenced in the response that are not contained in the storage medium accessible by the application further comprises requesting from the network node, without further user intervention, the one or more objects referenced in the response that are either not contained in the storage medium accessible by the application or are contained in the storage medium but are stale;

receiving the one or more objects referenced in the response that are not contained in the storage medium accessible by the application further comprises receiving the one or more objects referenced in the response that are either not contained in the storage medium accessible by the application or are contained in the storage medium but are stale; and

wherein, in response to a request from the application for an embedded object referenced in the response, the application accesses the storage medium if the requested object is contained in the storage medium and is not stale, and the application accesses the received one or more objects referenced in the response if the requested object is either not contained in the storage medium or is contained in the storage medium but is stale.

9. A method of providing a response to a request for a resource from an application, comprising:

obtaining information regarding the contents of a storage medium accessible by the application at a network node;

receiving a response to the request at the network node;

processing the response to identify one or more embedded objects referenced in the response;

identifying one or more embedded objects referenced in the response that are not contained in the storage medium accessible by the application;

requesting, without further user intervention, the one or more objects referenced in the response that are not contained in the storage medium accessible by the application;

receiving the one or more objects referenced in the response that are not contained in the storage medium accessible by the application;

wherein, in response to a request from the application for an embedded object referenced in the response, the application retrieves the object from the storage medium if the requested object is contained in the storage medium and the application accesses the received one or more objects referenced in the response that are not contained in the storage medium if the requested object is not contained in the storage medium.

10. The method of claim 9, wherein obtaining information regarding the contents of a storage medium accessible by the application at a network node further comprises receiving the information as a part of the request from the application.

11. The method of claim 10, wherein receiving the information as a part of the request from the application further comprises receiving the information as a modification to a protocol used to control communication of the request.

12. The method of claim 9, wherein the obtained information is regarding the contents of the storage medium that are relevant to responding to the request.

13. The method of claim 9, wherein the application is a browser.

14. The method of claim 9, wherein

receiving the one or more objects referenced in the response that are not contained in the storage medium accessible by the application further comprises receiving the one or more objects referenced in the response that are not contained in the storage medium accessible by the application and providing the one or more objects to another network element;

and

wherein, in response to a request from the application for an embedded object referenced in the response, the application retrieves the object from the storage medium if the requested object is contained in the storage medium and the application accesses the received one or more objects referenced in the response that are not contained in the storage medium from the another network element if the requested object is not contained in the storage medium.

15. A method of processing a request for a resource by an application, comprising:

determining contents of a storage medium accessible by the application;

incorporating information regarding the contents of the storage medium into the request;

receiving a response to the request, wherein the response includes references to a plurality of embedded objects, the embedded objects including an object contained in the storage medium and an object not contained in the storage medium accessible by the application;
