Asp.net中的Server,Session,Application.Global.asax

不同的对象有不同的作用; 
              Server(UrlEnCode,mapath,HtmlEnCode,Server.excute)
              Session(session_start,session_end,sessionID,lcid,count.session.timeout=1)
              Application(1,先在grobal.asax可以设置Application.start{//连接,int(object)Application["total"]=Count},
                                 2,在Session_Start中设置,  Application.lock(),Application["total"]=(int)Application["tatol"]+1; 记得关掉Application.unlock(); This. lblshow.text=Applicaton["total"].ToString();
                                 3,在Application_end中update记得转换和执行.update ? set num=+"Application["total"].ToString)
