Sure. If Apache sends compressed content it should also send a
"Vary: accept-encoding" along so Varnish will _vary_ the content
depending on the content of that header. If the backend doesn't
you might send compressed content to someone you hasn't indicated
that they support it.

This was discussed here a couple of weeks back, I think. Try searching
the archives.
