Abstract

Features are disclosed for determining which content item or items are likely to be requested by a particular user or device, or by a group of users or devices. The determined content items may be obtained independently of a request from the users or devices, and substantially current versions of the content items may be maintained at a server system, such as an intermediary system. Visual representations of the content items may be generated to reduce processing requirements at a user device. When the content items are determined to be likely to be requested by a particular user, a predicted time may also be determined, and the visual representations may be generated such that they are available at the predicted time.

Claims

1. A system comprising one or more server computing devices programmed to at least:

determine, based at least on prior request data associated with a user, a content item likely to be requested by the user and a time at which the user is likely to request the content item;

responsive to a determination that a current time is within a selected range of the determined time, determine a server-based rendering engine of a plurality of server-based rendering engines, separate from a user computing device of the user, that is rendering the content item; and

responsive to a subsequent request for the content item from a user computing device operated by the user, establish a remote connection between the server-based rendering engine and the user computing device, such that the user computing device may access the rendered content item,

the system thereby reducing a user-perceived load time for the content item relative to a load time for loading the content item from the content server.

2. The system of claim 1, wherein the one or more server computing devices are further programmed to maintain a substantially current rendered version of the content item in the server-based rendering engine for a period of time, the period of time including the determined time.

3. The system of claim 2, wherein the one or more server computing devices are further programmed to maintain the substantially current rendered version of the content item by periodically polling the content server.

4. The system of claim 1, wherein the remote connection is established using a remote session communication protocol.

5. The system of claim 1, wherein one or more server computing devices are further programmed to provide a visual representation of the rendered content item to the user computing device via the remote connection.

6. The system of claim 1, wherein the one or more server computing devices are further programmed to transmit a substantially current copy of the content item to the user computing device subsequent to the user computing device accessing the rendered content item at the one or more server computing devices.

7. The system of claim 1, wherein the one or more server computing devices are further programmed to:

receive, from the user computing device, a plurality of requests for content items; and

store prior request data reflecting at least a portion of the plurality of requests, the prior request data associated with the user.

25. The system of claim 1, wherein determining a server-based rendering engine of a plurality of server-based rendering engines, separate from a user computing device of the user, that is rendering the content item comprises:

causing the server-based rendering engine to initiate rendering the content item.

8. A computer-implemented method comprising, as executed by one or more server computing devices:

identifying, based at least on content request data reflecting content requests from a subset of a plurality of user computing devices, a content item likely to be requested by a user computing device of the subset;

in response to identifying the content item, maintaining, by a server-based rendering engine of a plurality of server-based rendering engines assigned to the subset, a substantially current version of the content item without receiving a request for the content item, the substantially current version comprising a processed visual representation of the content item; and

in response to a request for the content item from a first user computing device of the subset, providing the first user computing device with access to the substantially current version of the content item.

9. The computer-implemented method of claim 8, further comprising:

receiving a plurality of content requests from the plurality of user computing devices, the plurality of requests corresponding to content items hosted by content servers separate from the one or more server computing devices; and

storing content request data reflecting at least a portion of the plurality of requests.

10. The computer-implemented method of claim 8, wherein the content item comprises at least one of a web page, an image, a video, or a document.

11. The computer-implemented method of claim 8, wherein providing the first user computing device with access to the substantially current version comprises establishing a connection with the first user computing device using a remote session communication protocol.

12. The computer-implemented method of claim 8, wherein providing the first user computing device with access to the substantially current version comprises providing a video feed of the content item as rendered by the server-based rendering engine.

13. The computer-implemented method of claim 8, wherein providing the first user computing device with access to the substantially current version comprises transmitting an image of the substantially current version.

14. The computer-implemented method of claim 8, further comprising transmitting a substantially current copy of the content item to the first user computing device subsequent to the first user computing device accessing the rendered content item at the one or more server computing devices.

15. The computer-implemented method of claim 8, further comprising:

maintaining a second substantially current version of a second content item, the second substantially current version associated with a second subset of the plurality of user computing devices.

16. The computer-implemented method of claim 15, further comprising assigning a user of the first computing device to the subset based at least on previous content requests initiated by the user.

17. The computer-implemented method of claim 15, further comprising assigning a user of the first computing device to the subset based at least on a characteristic of the first user computing device.

18. The computer-implemented method of claim 8, wherein the content request data is received from the first user computing device in conjunction with a request for a content item.

19. The computer-implemented method of claim 8, wherein the content request data is received from the first user computing device independently of any request for a content item.

20. The computer-implemented method of claim 8, wherein providing the first user computing device with access to the substantially current version of the content item comprises transmitting a plurality of content objects associated with the content item using at least two different communication protocols.

21. A non-transitory computer storage medium comprising a browser module configured to execute a process on a user computing device, the process comprising:

determining, based on prior content requests initiated by the user computing device, a first content item likely to be requested by the user computing device;

transmitting, to a server computing device, content request data regarding one or more content items likely to be requested by the user computing device;

transmitting, to the server computing device, a request for the first content item; and

in response to the request, accessing a visual representation of the content item rendered by a server-based rendering engine of a plurality of server-based rendering engines that is determined by the server computing device to be rendering the content item.

22. The non-transitory computer storage medium of claim 21, wherein the browser module comprises one of:

an application, a browser toolbar, or a browser add-in.

23. The non-transitory computer storage medium of claim 21, wherein accessing the visual representation comprises establishing a connection using a remote session communication protocol.

24. The non-transitory computer storage medium of claim 21, wherein the process further comprises receiving, in response to the request, a plurality of content objects associated with the content item using at least two different communication protocols.
