Abstract

The delivery of content is improved from a user'"'"'s perspective by encouraging the cache of user devices to maintain more current data prior to requesting web pages that would invoke the download of the more current data. A cache simulation of the cache in the user devices is maintained. When objects within the cache simulator are expected to require updating, actions are taken to encourage the user device to update the cache. The actions include modifying markup language files that are downloaded to the user device to invoke the update. For instance, artificial URL'"'"'s that request the updated objects, embedded scripts, user selection objects, or the like are used to invoke an update process.

Claims

1. A communication system for accelerating the presentation of displayable content, the system comprising:

one or more content servers with each content server comprising one or more sets of displayable content, wherein the one or more content servers are configured to respond to requests for delivering displayable content by transmitting a file that defines the displayable content;

one or more terminals, each terminal having an application for accessing the one or more content servers and requesting displayable content and a cache for caching portions of the displayable content contained within or defined by the transmitted file;

a network for connecting the one or more terminals with the one or more content servers; and

a cache updater server (CUS) that is communicatively coupled to the one or more terminals and the one or more content servers, wherein the CUS is capable of updating the portions of the displayable content stored at the caches of each one of the terminals prior to receiving a request for the displayable content from the application of the terminal.

2. The system of claim 1, wherein the CUS comprises a cache simulator of each one of the caches located on the terminals and the CUS is capable of updating each one of the cache simulators.

3. The system of claim 1, wherein the displayable content is defined in the transmitted file by a markup language.

4. The system of claim 3, wherein the transmitted file contains markup language instructions that define displayable content and references to other objects.

5. The system of claim 4, wherein the portions of the displayable content comprises objects.

6. The system of claim 2, wherein the CUS is capable of modifying the transmitted file to trigger the application for accessing the one or more content servers to request the updated portion of its cache.

7. The system of claim 2, wherein the application for accessing the one or more content servers is selected from a group consisting of:

Openwave Systems Inc. or OPERA MOBILE BROWSER and INTERNET EXPLORER.

8. The system of claim 1, wherein the CUS is connected as an intermediate node on the network between the one or more terminals and the one or more content servers.

9. The system of claim 1, wherein the CUS is transparent to the one or more terminals and to the one or more content servers.

10. An apparatus for automatically updating objects in a memory element associated with a user device (a cache), wherein the apparatus is communicatively coupled with a plurality user devices and one or more servers, the apparatus comprising:

a user database (UDB), wherein the UDB comprises information which is relevant for automatically updating the memory element of a user device that is communicating via the apparatus;

a module capable of;

determining which objects that are stored in the UDB are needed for updating the memory element of the particular user.

11. The apparatus of claim 10, wherein the module is further capable of:

a. receiving a file that is targeted toward a particular user, the file identifying one or more objects,

b. modifying the file to invoke an update of the objects in the memory element with the objects stored in the UDB; and

c. transferring the modified file toward the user.

12. The apparatus of claim 10, wherein the file is a markup language file that can be rendered by a user device, and the module is capable of modifying the file by changing the expiration date of the web page represented by the markup language file or the one or more objects in the markup language file.

13. The apparatus of claim 10, wherein the file is a markup language file that can be rendered by a user device, and the module is capable of modifying the file by adding artificial links into the markup language file that point to objects that need to be loaded into the memory element of the user device.

14. The apparatus of claim 13, wherein the artificial link points to a transparent object and is set to a value that does not exist in the memory element of the user device thereby causing the user device to access the UDB and receive updated objects.

15. The apparatus of claim 10, wherein the file is a markup language file that can be rendered by a user device, and the module is capable of modifying the file by adding a user selection object which, when selected issues a memory update request that results in one or more objects being loaded into the memory element of the user device to replace expired objects or add missing objects.

16. The apparatus of claim 10, wherein the apparatus further comprising a learning module for defining an update order.

17. A method for updating the cache of a user device, the method comprising the steps of:

a. simulating the state of the cache of the user device;

b. receiving a markup language file coming from a server toward the user device;

c. identifying at least one object in the simulated cache that needs updating at the user device;

d. modifying the received markup language file to invoke the updating of the cache of the user device; and

e. transferring the modified markup language file toward the user device.

18. The method of claim 17, wherein the step of simulating the state of the cache of the user device further comprises the steps of:

a. maintaining information on one or more objects that are assumed to be stored in the cache of user device;

b. determining which one of the assumed objects needs to be update;

c. fetching an updated object; and

d. storing the updated object in the simulated cache in the place of the old object.

e.

19. The method of claim 18, further comprises the steps of marking the updated object as an object to be delivered to the user device in order to update its cache.

20. The method of claim 17, wherein the step of modifying the markup language file further comprises the steps of:

creating an artificial link that is not in the cache of the user device;

associating the artificial link with objects to be downloaded to the cache of the user device; and

placing an artificial link within the markup language page, thereby invoking the user device to access the associated objects.

21. The method of claim 20, further comprising the step of downloading the associated object in response to the user device accessing the artificial link.

22. The method of claim 17, wherein the step of modifying the markup language file further comprises the steps of:

creating a user selection object;

associating the user selection object with objects to be downloaded to the cache of the user device; and

inserting the user selection object into the markup language file, thereby prompting a user to initiate a download of objects to update the cache.

23. The method of claim 22, further comprising the step of downloading the associated objects in response to an actuation of the user selection object.

24. The method of claim 17, wherein the step of modifying the markup language file further comprises the step of:

changing the expiration date of the web page represented by the markup language file or the one or more objects in the markup language file.

25. The method of claim 17, wherein the step of modifying the markup language file further comprises the steps of:

receiving a request from the user device;

modifying the response to the request by adding a script which when executed, initiates a request for updated objects.

26. The method of claim 17, further comprising the steps of:

observing user trends over a period of time;

detecting that the markup language file is a particular file in the observed trend;

identifying a probable next markup language file request based on the detected markup language file and the trend; and

modifying the markup language file to invoke the updating of objects in the probable next markup language file.
