Web API CORS support not working on http

I have enabled CORS support on my Web API controller and it works fine on https, but on http I'm still getting this o 'Access-Control-Allow-Origin' header is present on the requested resource error.

In WebApiConfig I have enabled cors by using this line:

// Allow cross site javascript calls
config.EnableCors();

And my controller class is introduced like this:

 [EnableCors("*","*","*")]
 public class ExternalDataController : ApiController

So how I can enable CORS on http and https?

On azure raw http logs following lines appear when I create a one call:

Do you use OWIN? Just enable CORS in your Configuration method:

    public void Configuration(IAppBuilder app)
    {
        #region CORS

        app.UseCors(CorsOptions.AllowAll); 

        #endregion

Sorry I have not checked at Controller level.

I have the following at WebApi config level and it is working as expected.

 var cors = new EnableCorsAttribute("*", "*", "*") ;
            config.EnableCors(cors);

Similarly if you are using Basic auth then make sure that you set SupportsCredentials value as well

        var cors = new EnableCorsAttribute("*", "*", "*") { SupportsCredentials = true };
