在实际开发过程中，往往我们需要从一个已知的URL跟踪其在网络中的重定向的地址列表，参考了查了一下资料，Stackoverflow上的解决方案:http://stackoverflow.com/questions/17990604/get-a-collection-of-redirected-urls-from-httpwebresponsepublic static string RedirectPath(string url)
{
StringBuilder sb = new StringBuilder();
string location = string.Copy(url);
while (!string.IsNullOrWhiteSpace(location))
{
sb.AppendLine(location); // you can also use 'Append'
HttpWebRequest request = HttpWebRequest.CreateHttp(location);
request.AllowAutoRedirect = false;
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
location = response.GetResponseHeader("Location");
}
}
return sb.ToString();
}
