If the job were changed to two
links deep, however, a total of 31 pages would need to be accessed. This could pose a
serious drain on the Internet bandwidth available if not configured properly.
Configuring Add-Ins
One of the biggest advantages to ISA Server 2006 is its ability to have its base applicationfiltering
engine easily extended with third-party add-in functionality. This makes ISA a
strong candidate for software to provide advanced web filtering, anti-virus applications,
intrusion detection filters, and additional VPN capabilities.

Configuring Add-Ins
All the add-ins to ISA Server, including the default add-ins that are installed with ISA
itself, can be viewed from within the Add-ins node of the console tree, as shown in Figure
3.34. This section takes a high-level look at the add-in options available in the Add-ins
node of the ISA Console. Additional information on specific add-ins can be found in Part
III of this book, ???Securing Servers and Services with ISA Server 2006.???
Exploring Application Filters
Application filters in ISA were specifically created to examine the traffic being passed
through the server and make sure that it is not simply a piggy-backed exploit or attack.
