Managing temporary storage settings

Article
02/25/2011

Updated: February 1, 2011

Applies To: Forefront Threat Management Gateway (TMG)

Web traffic may contain malware (such as worms, viruses, and spyware). Forefront TMG includes malware inspection for scanning, cleaning, and blocking harmful HTTP content and files. When malware inspection is enabled, downloaded Web pages and files allowed by access rules may be inspected for malware.

Forefront TMG temporarily stores downloaded content in physical memory or on disk during malware inspection.

By default, Forefront TMG uses the %SystemRoot%\Temp folder to temporarily accumulate and store files on disk during malware inspection. You can change the location for temporarily storing files for malware inspection in Forefront TMG Management.

In addition, several advanced settings that determine how downloaded content is stored during malware inspection can be configured programmatically. These settings are summarized in the following table.

Setting	Description
Disk storage threshold	Specifies the amount of memory used, in kilobytes, at which temporary storage will switch to disk. Its default value is 64 kilobytes, and its range of permissible values is from 4 through 256.
Maximum total storage size	Specifies the maximum total disk space, in gigabytes, that may be used for temporary storage. Its default value is 40 gigabytes, and its smallest permissible value is 4.
Client storage limit	Specifies the maximum disk space, in megabytes, that may be allocated for temporary storage for a single client. Its default value is 50 megabytes, and its smallest permissible value is 0.
Extended client storage limit	Specifies the maximum disk space, in megabytes, that may be allocated for temporary storage for a single client that has been granted the extended disk space storage limit. Its default value is 1024 megabytes, and its smallest permissible value is 0.
Extended limit pool size	Specifies the maximum number of clients that may be granted the extended disk space storage limit concurrently. Its default value is 20 clients, and its smallest permissible value is 0.

Forefront TMG, Medium Business Edition does not support a custom client storage limit, a custom extended client storage limit, or a custom extended limit pool size for client IP addresses that are included in the computer sets that list IP address exceptions. In particular, you cannot configure a custom client storage limit for a downstream proxy server on an upstream proxy server running Forefront TMG, Medium Business Edition in a Web chaining scenario.

Showing the temporary storage settings

The Microsoft Visual Basic Scripting Edition (VBScript) code in ShowTemporaryStorageSettings.vbs (listed later in this document) displays the programmatically configurable advanced settings that determine how downloaded content is stored during malware inspection in the local array.

This script, as presented, must be run on a Forefront TMG computer with the Microsoft Firewall service installed, but it can be modified to run on a remote management computer.

To use this script, paste the code in the script listing into a text editor, save it in a file named ShowTemporaryStorageSettings.vbs, and then run it from a command prompt.

Usage:

CScript ShowTemporaryStorageSettings.vbs

To show the temporary storage settings

Create an instance of the FPC COM object, which is known as the root object and provides access to the other Forefront TMG administration COM objects.
Get references to the FPCArray object, the FPCTemporaryStorageSettings object, and the FPCConnectionLimitPolicy object for the local array.
Display the values of the DiskStorageThresholdInKilobytes and MaxTotalStorageSizeInGigas properties of the FPCTemporaryStorageSettings object.
Display the values of the ClientStorageLimitInMegs, ClientExtendedStorageLimitInMegs, and ClientExtendedStorageLimitPoolSize properties of the FPCConnectionLimit object retrieved from the DefaultLimit property of the FPCConnectionLimitPolicy object.

Modifying the temporary storage settings

The VBScript code in SetTemporaryStorageSettings.vbs (listed later in this document) configures the programmatically configurable advanced settings that determine how downloaded content is stored during malware inspection in the local array.

This script, as presented, must be run on a Forefront TMG computer with the Microsoft Firewall service installed, but it can be modified to run on a remote management computer.

To use this script, paste the code in the script listing into a text editor, save it in a file named SetTemporaryStorageSettings.vbs, and then run it from a command prompt.

Usage:

CScript SetTemporaryStorageSettings.vbs [/d] [/dst:value] [/mts:value] [/csl:value] [/ecsl:value] [/eps:value] [/h | /?]

Here value specifies the value supplied for the applicable argument. The meanings of the arguments are summarized in the following table.

Argument	Meaning
/d	Restore the default values of the delivery delay, progress refresh delay, maximum retrieval time, and maximum repeated retrieval time.
/dst	Set the disk storage threshold to the value specified in value.
/mts	Set the maximum total storage size to the value specified in value.
/csl	Set the client storage limit to the value specified in value.
/ecsl	Set the extended client storage limit to the value specified in value.
/eps	Set the extended limit pool size to the value specified in value.
/h /?	Display the usage information.

After you run the script, check the Configuration tab for the Monitoring node to verify that the changes were applied.

To modify the temporary storage settings

Create an instance of the FPC COM object, which is known as the root object and provides access to the other Forefront TMG administration COM objects.
Get references to the FPCArray object, the FPCTemporaryStorageSettings object, and the FPCConnectionLimitPolicy object for the local array.
Do one of the following:
- If the /d argument is specified, restore the default values of the DiskStorageThresholdInKilobytes and MaxTotalStorageSizeInGigas properties of the FPCTemporaryStorageSettings object and the ClientStorageLimitInMegs, ClientExtendedStorageLimitInMegs, and ClientExtendedStorageLimitPoolSize properties of the FPCConnectionLimit object retrieved from the DefaultLimit property of the FPCConnectionLimitPolicy object.
- If the /d argument is not specified, change the values of the DiskStorageThresholdInKilobytes and MaxTotalStorageSizeInGigas properties of the FPCTemporaryStorageSettings object and the ClientStorageLimitInMegs, ClientExtendedStorageLimitInMegs, and ClientExtendedStorageLimitPoolSize properties of the FPCConnectionLimit object retrieved from the DefaultLimit property of the FPCConnectionLimitPolicy object to the values specified by the user.
Call Save on the FPCArray object to write the changes to persistent storage.
