NCSA Mosaic for the Macintosh User Guide: Advanced Features
Access authentication restricts access to a server based on one of the following:- username- or password-level access authorization
- connection rejection or acceptance based on Internet address
- a combination of the above two methods
The NCSA httpd software (which establishes and runs a World Wide Web server) lets you restrict two aspects of your Web document tree. You do not know that a server is running access authentication until you try to connect to the server. A dialog box from the server appears in your window requesting your login name and a password. If you do not pass the authentication test(s) you are denied access to the server.
