| Microsoft Internet Security and Acceleration Server 2000 |
Microsoft® Internet Security and Acceleration (ISA) Server 2000 is a platform that third-party developers can extend by creating components that work with ISA, such as application filters, ISA Management, and Web (ISAPI) filters. For example, a vendor may develop an application filter that scans for viruses. The filter configuration information should be included with ISA configuration information. When ISA is backed up, the virus-scanning filter configuration data is also backed up. The mechanism for integrating third-party data into ISA is the FPCVendorParametersSets collection.
Developers can also create Microsoft Management Console (MMC) extension snap-ins for components designed to work with ISA, so that relevant property pages will be integrated into ISA Management.
ISA provides extensive support for administration of ISA arrays, either using ISA Management, as described in the product documentation, or through administration scripting.
The Msfpccom.idl source file contains the definitions of all ISA administration COM objects. In Visual Basic, you access the administration COM objects through the FPCLib type library. The Wspfwext.idl source file contains the definitions of all ISA Firewall interfaces.
Within the ISA Software Development Kit (SDK), the following topics contain example code that can be copied from the text:
In addition to the example code in the SDK, the following samples are on the ISA Server CD-ROM in the sdk\samples\Admin\Scripts folder. The file name of each sample is listed in the Samples column. A brief description and the language extension are also provided. See Script Samples for more detailed descriptions.
| Samples | Description | Language |
|---|---|---|
| Add_Dod | Shows how to add a new Dialup Entry. | VBScript |
| AddDeniedMethod | Shows how to add a denied HTTP method. | VBScript |
| AdditionalKey | Demonstrates the use of the additional key. | VBScript |
| AddLATEntry | Shows how to add an IP range to the array LAT. | VBScript |
| AddScheduledContentDownload | Adds a scheduled content download job. | VBScript |
| ApplicationFilterList | Lists the Application Filters installed on the ISA server. | VBScript, JScript |
| CacheSettings | Displays array cache settings. | VBScript, JScript |
| ConstructLAT | Shows how to construct the LAT of an array based on its network interface cards (NICs). | VBScript, JScript |
| DeleteURL | Causes the Web proxy service to delete a Web object from the ISA cache. | VBScript |
| DisableScheduledContentDownload | Disables ScheduledContent Download on given days for a given array. | VBScript |
| EnterpriseDestination | Adds a new Destination Set to the Enterprise, sets the array policy to use Array And Enterprise Policies, and configures the new rule to use the Enterprise Destination. | VBScript |
| FetchUrl | Causes the Web proxy service to fetch an object and store it in the cache. | VBScript |
| FindScheduledContentDownload | Receives an array name and a URL and checks if any scheduled content download job includes that URL. | VBScript |
| ListDeniedMethods | Lists the denied HTTP methods for an array. | VBScript |
| ListServers | Lists servers in a given array. | VBScript, JScript |
| SetCache | Sets the cache. | VBScript |
| SetDefaultApplicationSettings | Demonstrates how to add client settings. | VBScript |
| SetUpstreamRouting | Shows how to set up upstream routing to another server. | VBScript |
| ShowAllProtocolRules | Lists all protocol rules of an array. | VBScript, JScript |
| ShowAllRoutingRules | Lists all routing rules of an array. | VBScript |
| StaticFilter | Demonstrates how to create a static packet filter, which allows NTP communication with the ISA Server computer. NTP uses the UDP protocol and Port 123. | VBScript |
Note The JScript samples have limited functionality compared to the corresponding VBScript samples. The major difference is that JScript will always use the first array in a network, whereas VBScript will ask the user for the array name.
The following application filter samples are on the ISA CD-ROM in the sdk\samples\application_filters folder. The file name of each sample is listed in the Samples column. The samples are written in C++. For more details regarding the samples, see Sample Filters.
| Samples | Description |
|---|---|
| Connector | A console application that emulates an application protocol (works with ConnectorFilter). |
| ConnectorFilter | Enables a complex protocol that requires secondary connections on random ports (works with Connector application). |
| DbgDump | Registers for notifications on all possible events, installs data filters on all connections, and outputs information about the events to the debugger. |
| Exeblock | Blocks all executable files unless a protocol rule is defined allowing a specific user to receive executable files. |
| Serversplit | Demonstrates the use of connection emulation for inbound connections. |
| SMTPFLTR | Captures and analyzes data sent by external clients that use the SMTP protocol. |
| Socks4a | Demonstrates the use of SOCKS protocol version 4/4A. |
| Socks5 | Demonstrates the use of the SOCKS 5 protocol. |
The Web (ISAPI) filter sample WebResponseModifier is provided on the ISA Server CD-ROM in the sdk\samples\Web_filters folder. The filter collects response chunks and allows you to change them depending on the complete response.
For more details about the WebResponseModifier sample, see Webresponsemodifier.
