System and method of performing domain name server pre-fetching
First Claim
1. A method for performing Domain Name Server (DNS) pre-fetching of information for a portable computing device, the method comprising:
- rendering a web page on a display screen of the portable computing device;
detecting links on the rendered web page;
determining that a screen changing operation is being performed, wherein the screen changing operation is selected from the group consisting of scrolling, panning, zooming, and combinations thereof;
placing one or more DNS pre-fetch tasks for one or more of the detected links in a queue within the portable computing device when the screen changing operation is performed; and
determining that the screen changing operation is stopped; and
in response to determining that the screen changing operation has stopped, executing one or more of the DNS pre-fetch tasks in the queue.

Abstract
A method and system for performing domain name service (DNS) pre-fetching, content pre-fetching, or a combination thereof, are disclosed for a wireless portable computing device (PCD). The system and method may include rendering a web page on a display screen of the PCD and performing a DNS pre-fetch for any visible links within the web page. Further, the method may include determining whether a screen changing operation (i.e., a scrolling operation) is being performed and placing one or more DNS pre-fetch tasks in a queue for each link that is displayed on the display screen when the screen changing operation is performed. The method and system may reduce wait times for a wireless PCD when it is rendering webpages on its display screen.
