Notes

To open ISA Server Management, click Start, point to All Programs, point to Microsoft ISA Server, and then click ISA Server Management.
For ISA Server 2006 Enterprise Edition, expand Microsoft Internet Security and Acceleration Server 2006, expand Arrays, expand Array_Name, and then click Firewall Policy.

Important

When you apply an application filter, that filter will perform additional filtering functionality.
When you disable an application filter that typically applies to a protocol, you disable all application filter functionality. For example, by disabling the Web Proxy Filter for the HTTP protocol, you disable all caching and proxying for that protocol.
After you click Apply in the details pane, the policy is updated. The new policy applies only to new connections.
