Exactly my thoughts as well.  If the Vary header were in the response, then
mod_cache would act accordingly.

Without that header, every HTTP cache in between the client and the server
would operate identically to mod_cache as a quick_handler.  So, this doesn't
actually fix the problem if mod_rewrite is lame.  In short, this patch doesn't
fix anything and only hides the underlying cause.  -- justin
