Question

我有一个网站，我在其上运行了woorank报告。其报告的一个项目是：

www resolve Be careful! Your website without www doesn't redirect to www (or the opposite). It's duplicate content! Hide advice
High impactEasy to solve
Be sure that http://mysite.com and http://www.mysite.com are not running in parallel.

Redirecting requests from a non-preferred hostname is important because search engines consider URLs with and without "www" as two different websites.

Once your preferred domain is set, use a 301 redirect for all traffic to your non-preferred domain.

我在线阅读了一些帖子，并想知道在asp.net 4中修复此问题的 QUICK AND EASY 解决方案。

感谢。

有完全相同的问题，用我的全局asax修复它如果你要求我的网站没有www，我基本上会用301重定向你。顺便说一句，你很可能不需要if（url重写）的东西。只需要在其他地方完成工作。

void Application_BeginRequest(object sender, EventArgs e)
        {
            try
            {
                if (HttpContext.Current.Request.Url.AbsoluteUri.ToLower().StartsWith("http://mysite"))
                {
                    string newUrl = string.Empty;
                    if (HttpContext.Current.Items["UrlRewritingNet.UrlRewriter.VirtualUrl"] != null)
                        newUrl = "http://www.mysite.com" + HttpContext.Current.Items["UrlRewritingNet.UrlRewriter.VirtualUrl"].ToString();
                    else
                        newUrl = HttpContext.Current.Request.Url.AbsoluteUri.ToLower().Replace("http://mysite", "http://www.mysite");



                    Response.Status = "301 Moved Permanently";
                    Response.StatusCode = 301;
                    Response.StatusDescription = "Moved Permanently";
                    Response.AddHeader("Location", newUrl);
                    Response.End();
                }
            }
            catch (Exception ex)
            {
                Response.Write(ex.Message);
            }
        }

301重定向为seo
