The following directive specifies the order deny,allow and the Require directive for this directory. In this command, the server first evaluates the Deny directive for the GET method, which denies all access to this directory. Then, the server evaluates the Allow directive, which allows clients from .ni.com to GET files from this directory. Finally, the server evaluates the Require user authentication directive and allows only users named bob or users in the group developers access to this directory.
<Limit GET>
order deny,allow
deny from all
allow from .ni.com
require user bob
require group developers
