AllowOverrideList
permite restringir ainda mais as diretivas .htaccess para a lista especificada.
Citação dos documentos:
When this directive is set to None and AllowOverride is set to None, then .htaccessfiles are completely ignored. In this case, the server will not even attempt to read .htaccessfiles in the filesystem.
Example:
AllowOverride None AllowOverrideList Redirect RedirectMatch
In the example above, only the Redirect andRedirectMatch directives are allowed. All others will cause an internal server error.
Example:
AllowOverride AuthConfig AllowOverrideList CookieTracking CookieName
In the example above, AllowOverride grants permission to the AuthConfig directive grouping and AllowOverrideList grants permission to only two directives from the FileInfo directive grouping. All others will cause an internal server error.
