内网网址检查 [英] Intranet url checking

问题描述

public partial class _Default : System.Web.UI.Page
    {
       public static bool UrlIsValid(string url)
       
       {    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 
           request.Proxy = null;  
           try
    {        HttpWebResponse response = (HttpWebResponse)request.GetResponse();     
               
               return true;    }  
           
           catch //If exception thrown then couldn't get response from address  
           {        return false;    }
       }
        private void Page_Load(object sender, EventArgs e)
        {    Response.BufferOutput = true;
        string url = (" http:///");    
            if (UrlIsValid(url))  
            {        Response.Redirect(url);    }  
            else
    {        Response.Redirect("http://www.yahoo.com");    }

非常感谢您将此代码提供给我，但我也希望它也检查Intranet网站.因此，在那种情况下，尽管服务器已启动并且正在工作，但我仍要给公司Intranet网站提供服务时，我应该如何修改代码cos，并将其重定向到yahoo.我希望它仅在该Intranet站点内部站点已关闭或无法正常工作时才进行重定向.

请提供帮助..
