我关掉IE的META刷新后，不久上ikaka是一个空白，看源代码，哈，狐狸尾巴出来了，电信的“强制PORTAL”功能。
<HTML><script language="JavaScript">
function newwin()
{
var urlname;
var win_attr;
win_attr='toolbar=no,menubar=no,scrollbars=yes,status=no,
location=no,resizable=yes,fullscreen=no,directories=no,width=680,height=580,top=0,left=0 ';
window.open('http://ad.greenet.cn/push/hn0629/hn.htm','ips_win0',win_attr);
win_attr='toolbar=no,menubar=yes,scrollbars=yes,status=no,
location=no,resizable=yes,fullscreen=no,directories=no,width=400,height=500,top=0,left=0 ';
window.open('http://ad.greenet.cn/push/hn0711/index.htm','ips_win1',win_attr);
}
