Web Filter Setup

To set up a filter, use the FPCWebFilter and FPCWebFilters COM objects. Each FPCWebFilter object is defined by the globally unique identifier (GUID) used to add it to the FPCWebFilters collection.

To enable installed Web (ISAPI) filters, you need to stop and then restart the ISA Web proxy service.

Provided here are examples showing how to add a filter, change its priority, enable it, disable it, and delete it. Each example includes code for Microsoft® Visual Basic®, and Visual Basic Scripting Edition (VBScript):

• Adding a New Filter
• Changing Filter Order
• Disabling a Filter
• Enabling a Filter
• Deleting a Filter

Note  You can also write code into a Web filter so that it can be registered and unregistered from the command line, and added to ISA Management. This is described in Self-Registering Web Filters.
