ASP.NET如何清除指定COOKIE

清除cookie有两种个方式：一个是在服务端清除，一个是在客户端清除  

服务端清除cookie： 

1。Request.Cookies.Remove(name);//清除指定Cookie 

2.Request.Cookies.Clear();//清除所有Cookie  客服端js操作cookie //读取cookies函数 

 function getCookie(name)       

 {     var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));   

  if(arr != null) return unescape(arr[2]); return null; }  //删除cookie function delCookie(name) {     var exp = new Date();     exp.setTime(exp.getTime() - 1);     var cval=NewGetCookie(name);     if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString(); }  //添加Cookie function setCookies(name,value) {     var Days = 30;     var exp  = new Date();     exp.setTime(exp.getTime() + Days*24*60*60*1000);     document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString(); }
