Session和Cookie的一些基本操作

1、在session里面添加值:

Session.Add( " provider " , Doker.WebSite.AppCode.Global.CurrentUser.UserName);

获取session里的值

if  (Session[ " provider " ]  !=   null ) 
{
         string provider =  Session["provider"].ToString();
}

删除session

Session.Abandon();
Session.Clear();

在Web.config里面的session的设置

     < sessionState mode = " InProc "  stateConnectionString = " tcpip=127.0.0.1:42424 "  sqlConnectionString = " data source=127.0.0.1;Trusted_Connection=yes "  cookieless = " false "  timeout = " 50 " />

      我用session保存用户权限，我的系统是一个上传大文件，一般是50M，为什么在本地测试session都不会场丢失，而一放到服务器上，用户反应上传大文件里，系统很容易退出？希待网友，帮我解决，先谢谢！于是我决定改成cookie保存用户的权限！
 2、给cookie赋值

                    HttpCookie aCookie  =   new  HttpCookie( " provider " );
                    aCookie.Value  =  Doker.WebSite.AppCode.Global.CurrentUser.UserName;
                    aCookie.Expires  =  DateTime.Now.AddDays( 1 );
                    Response.Cookies.Add(aCookie);

获取cookie的值

                 if  (Request.Cookies[ " provider " ]  !=   null ) 
                 {
                    string provider = Server.HtmlEncode(Request.Cookies["provider"].Value); 
}   

删除cookie的值

            HttpCookie aCookie;
             string  cookieName;
             int  limit  =  Request.Cookies.Count;
             for  ( int  i  =   0 ; i  <  limit; i ++ )
             {
                cookieName = Request.Cookies[i].Name;
                aCookie = new HttpCookie(cookieName);
                aCookie.Expires = DateTime.Now.AddDays(-1);
                Response.Cookies.Add(aCookie);
            }
