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.
