//  HTTP_REFERER 是定義在http protocol的標頭資訊，若非來自非同步的request，值為null
//  REMOTE_ADDR 來源IP
//  感謝克里斯大大提供

string referer = Request.ServerVariables["HTTP_REFERER"];
string remoteAddr = Request.ServerVariables["REMOTE_ADDR"];
if((referer != null && referer.IndexOf("163.29.7.165") > -1) || remoteAddr == "163.29.7.165")
{
  //: your content is in here. 
}
