Answer 1

        Response.Headers.Append("myCaptchaName", "value");


services.AddCors(options =>
        {
            options.AddPolicy("AllowMyOrigin",
                builder => builder.WithOrigins("http://localhost:4200").AllowAnyHeader().
                AllowAnyMethod().AllowCredentials()
                .WithExposedHeaders("myCaptchaName"));
        });
        services.Configure(options =>
        {
            options.Filters.Add(new CorsAuthorizationFilterFactory("AllowMyOrigin"));
        });
