Demonstrates how to use user names, passwords and access groups. The application consists of an index page with links to three additional pages with access group numbers 0, 1 and 2.

Group 0 = Open access
Group 1 = Admin access
Group 2 = User access

The function HTTP_ACCESS CheckHttpAccess(int sock, int access_level, HTTP_Request & Req) is used to authenticate the user names and passwords.

Note: A web browser will cache the username and password once entered. To force a password request again you will need to clear the browser cache, restart the browser, or open a new private browsing session.
