//这里设置你的web地址，可以随便指向你的任意一个aspx页面甚至不存在的页面，目的是要激发Application_Start
//string url = "http://www.qumiao.com";手机主题
string url = "http://localhost:82/111.aspx";
HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
Stream receiveStream = myHttpWebResponse.GetResponseStream();//得到回写的字节流
