Why it was not happening on my local server at home, but once it goes to the internet public domain, it happends all the time.

先要问问你要干吗？HTTP的header只能发送一次。我估计你用的服务器server在你的code之前发了些banner，这样你就不能调用header了。如果是jump to other page,用javascript吧。

我一般用这样一个functionfunction redirect($url, $target="top") {
if(headers_sent()) {
print('<html><head><script language="javascript" type="text/javascript"> window.'.$target.'.location="'.$url.'"; </script></head></html>');
die();
} else {
header("location: ".$url);
exit;
}
}

终于找到原因了。不是因为我的服务商在我的页面里发了BANNER，是由于文件在上传时，setting 文件的最后多了几个空行。是在<?php ... ?>后多了几个空行。以前从来没有碰到这个问题。删除空行后，什么都不用改了。
I am sooooo happy.
