You can try the cache_peer option login=PASSTHRU for the config of new
proxy. It should work, but has not exactly had wide usage so there may
still be bugs not found.

Also your new frontend cannot do any authentication with the client when
using that option for auth types more complex than Basic or Bearer. The
credentials have to be transparently passed between the parent proxy and
the end-client to avoid confusing either of them about the auth state.
