访问cgi，提示找不到，404错误

hhl00

<VirtualHost *:80>
    DocumentRoot /home/vhosts/test/htdocs
   ScriptAlias /cgi-bin/ /home/vhosts/test/cgi-bin
    ServerName test.com
    CustomLog "|/usr/local/sbin/cronolog /var/log/httpd/access_log/%Y/%m/test_access_log" combined
</VirtualHost>

我这样配置，然后
http://www.test.com/cgi-bin/test.cgi  ，提示404错误，也就是找不到改文件。我错在哪里啊！
