请教一下高手,帮我看下面这个程序的作用是什么啊?不懂的是第三行"var re=..."
<script language="javascript"> < ! --
var url = location.search;
var re=/^?(.*)(select%20 insert%20 delete%20from%20 count( drop%20table update%20truncate%20 asc( mid( char( xp_cmdshell exec%20master net%20localgroup%20administrators " : net%20user ' %20or%20)(.*)$/gi;
var e=re.test(url);
if (re) {
alert("地址中含有非法字符～");
location.href="index.asp";
}
//-->
</script>
