一个关于Apache的初级问题，请大家帮帮忙

etarip

我在/var/www/cgi-bin/ 下放了一个first.cgi文件：

#!/usr/bin/perl
print "Content-type: text/html\r\n\r\n";
print "Hello, World.";


httpd.conf里的 AddHandler cgi-script *cgi前#已经去掉，

但在浏览器输入http://****/cgi-bin/first.cgi
之后总出现以下错误：

Server error!
The server encountered an internal error and was unable to complete your request.
Error message:
Premature end of script headers: first.cgi
If you think this is a server error, please contact the webmaster
Error 500


我刚看了apache的error log，没什么实际信息

[Mon Apr 12 18:38:27 2004] [error] [client ××××] Premature end of script headers: first.cgi


我是个初学者，请大家多多指教
