Drawing into question the safety of Google’s indexing system, the Web site all-in-one-business.com managed to “hijack” Google’s position in its search results with a 302 server redirect. Following the redirect, a query for “Google AdSense” returned results pointing to the unrelated site, rather than Google itself.
This type of incident can happen because of the way that Google implements the W3 HTTP specification. 302 redirects temporarily swap one domain name with another using rudimentary scripting. The spirit and letter of the specification requires Google to infer that content hosted by the 302 target is owned by the party doing the redirect.
