Abstract

A method and apparatus are provided for prefetching electronic data (e.g., a web page, HTML, a document, an image) viewable in a browser. When a browser is opened to a web page (or other form of electronic data) that contains links (e.g., hyperlinks) to other content, content described by one or more of the links is prefetched. In particular, the content is retrieved before a user operating the browser selects any of the links. As a result, an enhanced browsing window can be very rapidly displayed when the user does select one of the prefetched links. Links on the browser page may be selected and/or prioritized for prefetching in several ways—by automatically selecting some or all links, by using a template customized for the page, by applying heuristics to identify links meeting certain criteria, etc.

Claims

1. An automated method of prefetching a second page of electronic content identified by a first page, the method comprising:

retrieving data for facilitating identification of links to pages of electronic content;

when a first page of electronic content is browsed, identifying within the first page one or more links to other pages of electronic content, including a first link to a second page;

prioritizing the one or more links;

for each of the one or more links, prefetching content from a page of electronic content identified by the link;

constructing, without displaying, an enhanced browsing window comprising said prefetched content for the first link;

detecting placement of a user interface cursor proximate to the first link; and

in response to said detecting, displaying said enhanced browsing window.

2. The method of claim 1, further comprising, after said prefetching of content from the second page:

altering an appearance of the first link.

3. The method of claim 1, further comprising:

retrieving a set of ads relevant to the second page.
