Abstract
A signal-bearing medium is disclosed that includes operations including establishing a link threshold, wherein a web page will be assessed as lacking currency if a percentage of hyperlinks contained in the web page that link to an active page is less than the link threshold, accessing a web page containing hyperlinks, and testing the hyperlinks. Testing includes: selecting a hyperlink; and monitoring a number of redirects encountered by following the selected hyperlink until a final web page is reached or a failure occurs, and assessing the selected hyperlink as linking to a dead web page if a redirect limit is exceeded, the redirect limit greater than one, wherein exceeding the redirect limit causes occurrence of a failure. The operations also include calculating a percentage of hyperlinks that return active web pages, and comparing the percentage of hyperlinks that return active web pages with the link threshold.
