Recently the question was asked, "what does it mean, Options All?" Here is the quick answer..
When you see this in an .htaccess file:
That tells Apache to enable all options, except for
MultiViews. This is the default setting. The
Options directive controls which features are available in the directory (and subdirectories).
To override an option, you can do so like this:
Options All -Indexes
That directive will enable all default options except for
Indexes option controls whether or not directory views are enabled. You can disable multiple options like so:
Options All -Indexes -Includes
To disable all Apache options:
In this case, none of Apache's extra features will be enabled.
