    Use scheme-relative (aka protocol-relative) URLs for redirects
    
    This ensures that quark really does not care if the incoming connection
    is plain HTTP or relayed TLS-traffic from a proxy or tunnel. Depending
    on the previous negotiation, the client will make the right decision on
    which scheme to use in a given context.
