Primeiro de tudo: minha implicância, citada no manual sobre .htaccess arquivos:
You should avoid using .htaccess files completely if you have access to httpd main server config file. Using .htaccess files slows down your Apache http server. Any directive that you can include in a .htaccess file is better set in a Directory block, as it will have the same effect with better performance.
Em segundo lugar, mais leituras do manual também é útil:
The
IndexOrderDefault
directive is used in combination with theFancyIndexing
index option.
Tradução: inclua a opção FancyIndexing
na diretiva IndexOptions
.
Então, logo abaixo, no manual:
IndexOrderDefault takes two arguments. The first must be either Ascending or Descending, indicating the direction of the sort. The second argument must be one of the keywords Name, Date, Size, or Description...
Isso resulta no seguinte:
<Directory /some/path>
# Disable .htaccess files for performance:
AllowOverride none
# Enable automatic index generation for directories without a DirectoryIndex file
# and sort them by date:
Options +Indexes
IndexOptions FancyIndexing
IndexOrderDefault Descending Date
</Directory>
