Why not config cross-domain?

[xugy0926]

Sometimes, Services based on parse-server are part of the microservices.

Requests are forwarded through nginx, which handle cross-domains.

If parse-server also does cross-domain processing, this results in a double cross-domain.

Why not configure cross-domain processing of parse-server to switch?
