Adobe Streaming Server Cache-control headers

Hey,

We are using VOD streaming, but the adobe media streaming server is setting a "cache-control header of max-age=86400,public,must-revalidate,proxy-revalidate,no-transform".  Does anybody know how to "remove" the must-revalidate and proxy-revalidate options from being set?  The reason I want to remove these cache-control headers is that we use Wan optimization devices that will bypass optimization when seeing the specific cache-control headers of "must-revalidate and proxy-revalidate". 

thanks
