If a visitor is referred to a file on www.usask.ca that does not exist, they are shown the U of S custom "404 file not found" error page. If the page that referred them to this bad page is located at the U of S, the visitors are also shown a button that automatically reports this error to the webmaster for the referring page. The report lists the page containing the error, and what page it was trying to link to. This provides all the information required for the webmaster to fix the error.
Individual department webmasters do not have to do anything to enable this tool. It is done automatically by the central web coordinators. However, if you want the reports to go to a different e-mail address, you can contact the central webmasters to have the address changed.
To test this feature, build a link on your webpage to a site that does not exist on www.usask.ca. Then select this link from the web browser. You should see the "404 message" with the reporting button at the bottom. See the 404 page as an example.
