感謝回覆呢 ...

改成用單機去撈內容再補成
http://lcss.hinet.net/login-new.pl?form_auth=c07d2b65d94c1ecf5b91548e0b6d5602&username=xxx&password=zzz 就可以登入了 ...

但試著用 php 去撈內容再轉址, 同樣會被攔下來呢 ..
== example php ==
<html>
<body>
<?php
# id and password
$id=xxx;
$pw=zzz;
# open lcss.hinet and get form_auth id
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, "
http://lcss.hinet.net/login-new.pl?act=login");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_USERAGENT, "firefox");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$html= curl_exec($ch);
curl_close($ch);
preg_match("/value=\"(.*)\">/",$html,$value);
$vhinet = $value[1];
# jump to lcss.hinet.net
header ("Refresh: 0;
http://lcss.hinet.net/login-new.pl?form_auth=$vhinet&username=$id&password=$pw");
?>
</body>
</html>

連結的值看起來都對, 但應該還是少了什麼... 看來先乖乖打帳號密碼哩 !
