After you install ISA Server 2004 Service Pack 2 (SP2), you can configure the downstream ISA Server computer to cache content even if the upstream proxy server is configured to request client authentication. To configure the downstream ISA Server computer to cache content, change the
DontMarkSessionAsPrivateIfProxyAuthSeen parameter. To do this, follow these steps.
Note The
DontMarkSessionAsPrivateIfProxyAuthSeen parameter is the name of a vendor parameter set that can be modified after you install ISA Server 2004 SP2.
| 1. | Copy and paste the following code into Notepad:Sub AddDontMarkSessionAsPrivateIfProxyAuthSeen()
' Create the root object.
Dim root ' The FPCLib.FPC root object
Set root = CreateObject("FPC.Root")
' Declare the other objects that are required.
Dim array ' An FPCArray object
Dim VendorSets ' An FPCVendorParametersSets collection
Dim VendorSet ' An FPCVendorParametersSet object
' Obtain references to the array object

Set array = root.GetContainingArray
Set VendorSets = array.VendorParametersSets

| 2. | Save the file as "DownstreamISAcacheContent.vbs." |
| 3. | To run the code, type the following command at a command prompt:
cscript. DownstreamISAcacheContent.vbs Note You must run the code from the same location in which you saved the DownstreamISAcacheContent.vbs file in step 2. |
Notes| � | This code sets the DontMarkSessionAsPrivateIfProxyAuthSeen parameter to a value of 1. This value enables the downstream ISA Server computer to cache content even if the upstream proxy server is configured to request client authentication. |
| � | If you select the Content requiring user authentication for retrieval option when you create a cache rule in ISA Server 2004, the downstream ISA Server computer caches content from the upstream proxy server. The downstream server also caches content that is authenticated by any server, such as by a Web server. |
