<META HTTP-EQUIV="Content-Type" CONTENT="text/html;charset=gb2312">
<style>
@media all {CAP:clientCaps {behavior:url(#default#clientcaps)}}
</style>
<script for=window event=onload>
if (oClientCaps.connectionType=="online")
{
sType.innerText="Internet歡迎您！";
}
else
{
sType.innerText="怎麼沒有上網？";
}
</script>
</HEAD>
<BODY>
