Suppose we have files hello.html.en, hello.html.de and hello.html.fr The MultiViews option is enabled and the language priority is set as follows: LanguagePriority en de fr es Furthermore we have ForceLanguagePriority Fallback Now let start the server and send a request for hello.html with Accept-Language: sp; q=0.8, en; q=0.2, de; q=0.2, fr; q=0.2 As ForceLanguagePriority Prefer is not set, we should (according to http://httpd.apache.org/docs/2.2/mod/mod_negotiation.html ) we should get a http status 300 (MULTIPLE CHOICES). But when I run it actually I got hello.html.fr (!). So not only it does not conform to the documentation which implies that an error should be returned, but also intuitively the result is wrong as the logical choice would be english (as it is when Prefer specified).
FurtherMore: If we set ForceLanguagePriority None then as a response for the request for hello.html without Accept-Language header the french file was returned
