如何保护我的连接字符串？(How to secure my connection string? powershell + xml)

 你想要使用一个cookie，简单地将它设置为24小时后死亡，然后检查它是否已经过期如果它再次显示弹出窗口 
 
 //来自http://www.w3schools.com/的 Javascript版本示例 
 
function setCookie(cname,cvalue,exdays)
{
var d = new Date();
d.setTime(d.getTime()+(exdays*24*60*60*1000));
var expires = "expires="+d.toGMTString();
document.cookie = cname + "=" + cvalue + "; " + expires;
}

function getCookie(cname)
{
var name = cname + "=";
var ca = document.cookie.split(';');
for(var i=0; i<ca.length; i++) 
  {
  var c = ca[i].trim();
  if (c.indexOf(name)==0) return c.substring(name.length,c.length);
  }
return "";
}
if(getCookie('jquery_popup') ==""){
setCookie('jquery_popup','sessionexists',1);
//Add code to display popup here
}
 
 PHP方法 
 
if(!isset($_COOKIE['jquery_popup'])){
setcookie("jquery_popup", 'sessionexists', time()+3600*24); 
//Add code to display popup here
}

you would wanna use a cookie, simple set it to die after 24 hours and then check if it has expired if it has you show the popup again
