Class CorsOptionsMiddleware

Middleware to process OPTIONS requests when CORS is enabled.

This middleware is necessary because POST request don´t work even with CORS enabled. This is because browsers send an OPTIONS request before the POST request which is not proccesed by the Api.

This middleware is added by the CorsHandler class, so you don´t have to worry for adding it from the Startup.cs class.
