Abstract

Disclosed herein are methods and apparatus that improve the perceived responsiveness of a multi-server web site or web environment to web requests issued by web browsers. In one aspect, the methods and apparatus operate by determining a likely sequence of web pages to be accessed by users. The methods and apparatus then incorporate information identifying web pages and web page content likely to be requested later in the sequence in web pages responsive to web page requests received earlier in the sequence. In one such method, the URL of a second web is incorporated in a first web page that is expected to be requested before the second web page. A web client receiving the first web page will then issue a DNS request for address information corresponding to the URL of the second web page even if no request has been received for the second web page. Thus, the probability of a DNS system cache miss occurring when a web request for the second web page is actually received by the web client is significantly reduced.
