# still sending assets for plain HTTP requests from asset hosts. If you don't
# have SSL certificates for each of the asset hosts this technique allows you
# to avoid warnings in the client about mixed media.
# Note that the request parameter might not be supplied, e.g. when the assets
# are precompiled via a Rake task. Make sure to use a Proc instead of a lambda,
# since a Proc allows missing parameters and sets them to nil.
