> No, a preflight (OPTIONS) request is sent by the browser first prior to sending the request initiated by the application.

Note: preflight is not required for any type of request that browser js was capable of making prior to CORS being introduced. (Except for local network)

So a simple GET or POST does not require OPTIONS, but if you set a header it might require OPTIONS (unless its a header you could set in the pre-cors world)
