function Get() {
        $.ajax({
            url: "http://<web service domain>:31132/api/Customer",
            type: "GET",
            dataType: "json",
            contentType: "application/json;charset=utf-8",
            success: function (data) {

                $('#d').append("success");
            },
            error:function(){
                $('#d').append("Errorrr");
            }
        });
    }

        WebApiCorsConfiguration corsConfig = new WebApiCorsConfiguration();

        corsConfig.RegisterGlobal(httpConfig);


        corsConfig

          .ForResources("Customer")

          .ForOrigins("?????")// we need to register a client address access to webservice.This is my problem.

          .AllowAll();

    }
