From RFC 2854 [1]: | For documents labeled as text/html, the fragment identifier | designates the correspondingly named element; any element may be | named with the "id" attribute, and A, APPLET, FRAME, IFRAME, IMG and | MAP elements may be named with a "name" attribute. So, the frag id names an *element*, a structural part of the document. This increases my conviction that, if #Bob is a person, a 303 should be done before we serve HTML.

Even in the 3xx series, 303 is somewhat special. The HTTP spec says [2]: | The new URI is not a substitute reference for the originally | requested resource. The descriptions of other redirect codes don't have such language. The others can be understood as giving a new location for the requested resource. 303 is indeed "See Other", it points to an entirely different resource. In my interpretation at least.
