header是否可以改变HTML文件种类 比如404 400 200

[qqsweb]

(Status-Line) HTTP/1.1 404 Not Found
这个是文件不存在header给IE的信息
我试着在404.php中加入
header ('（Status-Line）: HTTP/1.1 200');
输出信息
(Status-Line) HTTP/1.1 404 Not Found
(Status-Line) HTTP/1.1 200
Connection Keep-Alive
Content-Type text/html
Date Sat, 22 May 2010 18:08:28 GMT
Keep-Alive timeout=15, max=100
Server Apache/2.0.63 (Win32) PHP/5.2.10
Transfer-Encoding chunked
X-Powered-By PHP/5.2.10

我希望404页面反馈给IE的信息是HTTP/1.1 200而不是HTTP/1.1 404 Not Found
这里头虽然有了200但IE只识别第一个提供的信息404文件不存在
改怎么做 是否可以改变？

在404.php中加入

header ('HTTP/1.1 200');

我在我的windows搭建的
Apache/2.0.63 (Win32) PHP/5.2.10
环境下可以正常
但在其他环境下都是依然显示404错误
Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635

但是使用301

header ('HTTP/1.1 301');

却可以下面是GOOGlE成功抓取到的HTTP头信息
HTTP/1.1 301 Moved Permanently
Date: Sun, 23 May 2010 01:10:41 GMT
