how can i light a scene in vray with an hdri but not have it show up in my reflections thru my windows

[gadzooks]

I have an interior space that i am lighting with a HDRI thru a dome light. I want it to light my scene and show in all my metal reflections inside the space, but not show up outside my windows how can I achieve this in vray? I want to use a different image outside my windows.
Thanks
