public ActionResult Details(int id,string slug)
{
    using (var productRepository = new EfProductRepository())
    {
        var product = productRepository.FindById(id);
        if (product == null) return RedirectToAction("Index","Home");
        if (product.SEOTextSlug != slug)
            return RedirectToAction("Details",new {id = product.ProductId,slug = product.SEOTextSlug});

        var model = new ProductDetailModel();

        //Load the product information.
        model.Product.ProductId = product.ProductId;
        model.Product.CoverImagePath = product.CoverImagePath;
        model.Product.Name = product.Name;
        model.Product.Tagline = product.Tagline;
        model.Product.Price = product.Price;
        model.Product.Stock = product.Stock;
        model.Product.PieceCount = (int)product.PieceCount;
        model.Product.SKU = product.SKU;

        //Load the reviews for that product.
        if (product.Reviews.Any())
        {
            foreach (var review in product.Reviews)
            {
                model.Reviews.Add(new Reviewmodel()
                {
                    ReviewId = review.ReviewId,AccountId = (int)review.AccountId,Content = review.Content,Location = review.Location,ProductId = (int)review.ProductId,PublishDate = review.PublishDate,ReviewRatingId = (int)review.ReviewRatingId
                });   
            }
        }

        return View(model);
    }
}

在这一点：

if (product.SEOTextSlug != slug)
    return RedirectToAction("Details",slug = product.SEOTextSlug});

我实际上正确地触发301重定向吗？

当然它正如我所希望的那样工作,但我想确保我返回正确的标准HTTP结果,以便搜索引擎正确响应它.
