--------------------------------------------------
.htaccess disabled             |  failure
forbidden directives (fatal)   |  failure       (highly unlikely, as it is part of core - but still possible)
access denied                  |  inconclusive  (it might be allowed to other files)
directive has no effect        |  failure
                               |  success
