网站尝试自动重定向的次数太多是什么意思？怎样解决？

private string GetHTML(string url, string cookie)
{
if (String.IsNullOrEmpty(url))
{
return null;
}
else
{
try
{
url = url.Replace(" ", "%20");
url = url.Replace("&", "&");
}
catch
{
}

}

string html = null;
string curCookie = null;
HttpWebRequest myRequest = null;
HttpWebResponse myResp = null;
StreamReader myReader = null;

for (int i = 0; i < 3; i++)
{

try
{
myRequest = (HttpWebRequest)WebRequest.Create(url);
myRequest.AllowAutoRedirect = false;
myRequest.Timeout = 60 * 1000;
myRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)";
myRequest.Headers.Add("Cookie", cookie);
myRequest.KeepAlive = true;
myResp = (HttpWebResponse)myRequest.GetResponse();
curCookie = myResp.Headers["Set-Cookie"];
curCookie = curCookie.Substring(0, curCookie.IndexOf(";"));
myReader = new StreamReader(myResp.GetResponseStream(), Encoding.Default, true);
html = myReader.ReadToEnd();

}
catch (Exception e)
{
// Console.WriteLine(e.ToString());
continue;
}
finally
{
if (myReader != null)
{
myReader.Close();
}
if (myResp != null)
{
myResp.Close();
}

}

if (html == null)
{
continue;
}
else if (html.IndexOf("Object moved") > 0) //手动获取转向地址,再次获取html代码
{
int pos1 = html.IndexOf("http://");
int pos2 = html.IndexOf("\">");
url = html.Substring(pos1, pos2 - pos1);
html = GetHTML(url, curCookie);
