Abstract

Everyone who has browsed the Internet has encountered a broken link resulting in an HTTP 404 - Not Found error. Unfortunately, when a document is missing due to a broken link, there are not many currently implemented recovery solutions. Internet Explorer will search the Internet via the user's indicated favorite search engine if the DNS server is unable to resolve the string provided in the address bar as a domain name, for example. This does not address, however, a situation where a user follows a broken link from within a domain. Upon encountering an HTTP 404 - Not Found error, a web browser can be empowered with functionality to attempt to locate the documents within domains as well. Web servers can also be empowered with mechanisms to assist the user in this regard.
