IIS6 Compression and WSS2

Hi

I have enable IIS6 compression via the IIS metabase and have seen great results when using the browser WSS2 sites. I am using a tool called Fiddler to monitor compressions performance.

The issue i am having is with office document in a document library. When i use save target as option from IE, Fiddler shows compression working. When i open the document the same document from MS Word or Excel, IIS compression does not seem to kick in.

Is their a way to configure my Office applications to work with IIS compression when i am opening documents from a document library is there something i am missing in my metabase configurations

Thanks,
AlexP
