I thought you said you have "multiple" servers but thousands of domains. In
that case, just list the servers by IP address and the proxy will pass the
Host header value as supplied by the client. You should probably avoid
using names resolved using DNS anyway so that a DNS hickup doesn't
effectively disable your proxy.
