全球301域名重定向到www.domain

Question

可我用的是开始的Global.asax请求重定向一切，

从mydomain.domain到www.mydomain.domain？

如果这是真的，我该怎么做？

Answer 1

protected void Application_PreRequestHandlerExecute(Object sender, EventArgs e) 
{ 
    string currentUrl = HttpContext.Current.Request.Path.ToLower(); 
    if(currentUrl.StartsWith("http://mydomain")) 
    { 
    Response.Status = "301 Moved Permanently"; 
    Response.AddHeader("Location", currentUrl.Replace("http://mydomain", "http://www.mydomain")); 
    Response.End(); 
    } 
} 

Answer 2

A到一月的回答微小的改动得到它的工作对我来说：

protected void Application_BeginRequest(Object sender, EventArgs e) 
{ 
    string currentUrl = HttpContext.Current.Request.Url.ToString().ToLower(); 
    if (currentUrl.StartsWith("http://mydomain")) 
    { 
     Response.Status = "301 Moved Permanently"; 
     Response.AddHeader("Location", currentUrl.Replace("http://mydomain", "http://www.mydomain")); 
     Response.End(); 
    } 
} 

变化是使用BeginRequest事件，并CURRENTURL设置为HttpContext.Current.Request.Url代替的HttpContext的.Current.Request.Path。请参阅：
