mod_speling would return either a 404 or a 30X.
:: detour to Apache docs ::
Whoops! This sounds like something I used to know and have forgotten (emphasis mine):
[If] only one document is found that "almost" matches the request, then it is returned in the form of a redirection response.
Doesn't say what kind of redirect. The only other server-generated redirect I can think of is the directory-slash one from mod_dir, which is a 301.
So that makes one more question for web2008: Does the change in browser's address bar reflect a response to a redirect header? There's no point in redirecting to a different casing if the server is going to redirect right back to another form. In fact that can't be all that's going on, because you would then have an infinite-redirect loop.
