Pages Access can be restricted according to user name, internet address, or both.
Access control can be tree-level, file level, or both.
If user-wise access control is used there has to be a password file listing all the users and their encrypted passwords. Group file contains declarations of groups containing users and other groups, with possibly an IP address template. The list of items is called a group definition. Group definition can be continued to next line after any comma in the definition. So in the previous example all the HTML files are accessible to willy and kenny, even those matching the two previous templates.
