You always may restrict access to some pages with a help of .htaccess. Use
require directives to to this.
Here is another way to do this. You may use the following attributes in pages or directory autohandlers to restrict access to some parts of your site.
Attributes are processed in given order. If any of them are true then access is allowed else redirect is made to /errors/require_xxx.htm page.
Requre user to be registered. Deny access for anonymous users.
Require user to be registered and be listed. Argument if array ref to list of valid user names.
Require user to be registered and be member of a group. Argument if array ref to list of valid group names.
Require user to be registered and be an admin.
You may overload some autohandler's method to add more functionality to a page.
<%method method_name> .. your code goes here return "something"; </%method>
Overloaded parent can be called as
<& PARENT:method_name, %ARGS &>

This method is called just after request processing preparation (check user, etc.) but before any content is sent to client. This method is useful for client events processing and handling redirects.
Any string returned is passed to redirect.mc to do external redirect.
This is the same functionality as
Title attribute. This method is used to make the Title be dynamic not static.
This is very last part of screen. Useful to show copyright messages
This method is used to show a menu on the left side of the screen. It returns an array or pairs.
<% method MenuItems> % return [ ['menu1' => 'http://...'], ['---' => '---'], ['html' => '<b>this is HTML</b>'] ]; </%method>
Every pair may be any of the following
