When the AuthFilter is notified of an incoming request, it automatically provides the following services regardless of the mode of operation:

• URL correctness. Detects whether the requested URL is correct, automatically correcting for the case sensitivity of the Internet Information Services (IIS) virtual directory roots.
  
  
• Cookie support. Checks for cookie support and, if unavailable, redirects the user to a no cookie page. Cookie support is required when using the AuthFilter.
  
  
• Ticket validation. Checks that the user has a valid ticket. A ticket is a set of property/value pairs set in the cookie of the user and used to identify or authenticate the user.

Additional services are provided, depending on the mode of operation of the filter.
