httpd.conf设置一个IP两个域名的方法

我就是不晓得如何让两个域名对应同一个IP，然后能识别出不同的网站？

NameVirtualHost 12.34.56.78  # your ip address
<VirtualHost 12.34.56.78>
        ServerName yourname1
        DocumentRoot yourpath1
</VirtualHost>
<VirtualHost 12.34.56.78>
        ServerName yourname2
        DocumentRoot yourpath2
</VirtualHost> Webjx.Com

If you want to use 443

NameVirtualHost 12.34.56.78:80  # your ip address
NameVirtualHost 12.34.56.78:443  # your ip address

<VirtualHost 12.34.56.78:80>
        ServerName yourname1
        DocumentRoot yourpath1
</VirtualHost>
<VirtualHost 12.34.56.78:443>
        ServerName yourname1
        DocumentRoot yourpath1
</VirtualHost>
