[web-devel] proxy with wai

[Michael Snoyman]

Probably the most expedient thing is to use `withFile` to get a Handle, and
then use `conduitHandle` instead of `conduitFile`. However, if you want to
use ResourceT, it's certainly possible, but a bit hairier:

        runResourceT $ withInternalState $ \is -> do
            respond $ WC.responseSource (HCl.responseStatus res) headers
                    $ C.transPipe (flip runInternalState is) body
