Pre-caching web content for a mobile device
View Patent ↗A web service for pre-caching web content on a mobile device includes receiving a request from the mobile device for first web content, fetching the first web content, determining second web content to pre-fetch based upon the first web content, fetching the second web content, and causing the second web content to be stored in a content cache on the mobile device responsive to the request for the first web content. Pre-caching web content in this manner provides web content to the mobile device that the user of the mobile device is likely to access. Pre-caching of additional web content prior to receiving an explicit request improves web browsing performance of the mobile device.
1. A method at a mobile device, the method comprising:
receiving a web request message for requested web content;
forwarding the web request message to a network proxy;
receiving the requested web content from the network proxy;
displaying, after the receiving, the requested web content;
determining that a number of links in the requested web content is greater than a threshold;
selecting links from the links in the requested web content based on usage patterns, the number of selected links being no greater than the threshold;
receiving additional content related to the requested web content at the mobile device, the additional content including all content identified by the selected links in the requested web content;
caching the additional content in a content cache at the mobile device;
receiving a user selection of a first link of the selected links in the requested web content;
retrieving, from the content cache at the mobile device, second web content identified by the first link from the content cache, the second web content being part of the additional content;
request, from the network proxy, second additional content related to the second web content, the second additional content including all content identified by links in the second web content;
receiving, from the network proxy, the second additional content; and
caching the second additional content.
2. The method of claim 1 , wherein the additional content is based on parsing of the requested content.
3. The method of claim 2 , wherein the additional content is further based on usage patterns from the mobile device.
4. The method of claim 3 , wherein the usage patterns include historical preferences for links from requested web content.
5. The method of claim 3 , wherein the usage patterns include historical preferences for non-linked web content.
6. The method of claim 1 , wherein the receiving the additional content is from a push server communicating with the network proxy.
7. A mobile device, comprising:
a processor;
a communications subsystem; and
memory,
wherein the mobile device is configured to:
receive a web request message for requested web content;
forward the web request message to a network proxy utilizing the communications subsystem;
receive the requested web content from the network proxy;
display, after the receiving, the requested web content;
determine that a number of links in the requested web content is greater than a threshold;
select links from the links in the requested web content based on usage patterns, the number of selected links being no greater than the threshold;
receive additional content related to the requested web content at the mobile device, the additional content including all content identified by the selected links in the requested web content;
cache the additional content in a content cache at the mobile device;
receive a user selection of a first link of the selected links in the requested web content;
retrieve, from the content cache at the mobile device, second web content identified by the first link from the content cache, the second web content being part of the additional content;
request, from the network proxy, second additional content related to the second web content, the second additional content including all content identified by links in the second web content;
receive, from the network proxy, the second additional content related; and
cache the second additional content.
8. The mobile device of claim 7 , wherein the additional content is based on parsing of the requested content.
9. The mobile device of claim 8 , wherein the additional content is further based on usage patterns from the mobile device.
10. The mobile device of claim 9 , wherein the usage patterns include historical preferences for links from requested web content.
11. The mobile device of claim 9 , wherein the usage patterns include historical preferences for non-linked web content.
12. The mobile device of claim 7 , wherein the receiving the additional content is from a push server communicating with the network proxy.
13. A non-transitory computer-readable medium comprising instructions in code which when loaded into a memory and executed by a processor of a mobile device cause the mobile device to:
receive a web request message for requested web content;
forward the web request message to a network proxy utilizing the communications subsystem;
receive the requested web content from the network proxy;
display, after the receiving, the requested web content;
determine that a number of links in the requested web content is greater than a threshold;
select links from the links in the requested web content based on usage patterns, the number of selected links being no greater than the threshold;
receive additional content related to the requested web content at the mobile device, the additional content including all content identified by the selected links in the requested web content;
cache the additional content in a content cache at the mobile device;
receive a user selection of a first link of the selected links in the requested web content;
retrieving second web content identified by the first link from the content cache, the second web content being part of the additional content;
request, from the network proxy, second additional content related to the second web content, the second additional content including all content identified by links in the second web content;
receive, from the network proxy, the second additional content; and
cache the second additional content.
14. The non-transitory computer-readable medium of claim 13 , wherein the additional content is based on parsing of the requested content.
15. The non-transitory computer-readable medium of claim 14 , wherein the additional content is further based on usage patterns from the mobile device.
16. The non-transitory computer-readable medium of claim 15 , wherein the usage patterns include historical preferences for links from requested web content.
17. The non-transitory computer-readable medium of claim 13 , wherein the usage patterns include historical preferences for non-linked web content.
