“如果服务器只有一个IP地址，用不同的端口号也能创建不同的虚拟主机”，该论述是 (8) 的。
A．正确 B．不正确

答案

参考答案：

解析：A或正确

[分析]： Web服务的默认端口号是80，但仍可以使用其他的端口号来配置新的Web服务，因此在基于IP的虚拟主机配置策略中，如果指定了IP地址和端口号，是可以有效区分Web虚拟站点的，例如在httpd.conf中使用以下配置行定义虚拟主机。 ＜VirtualHost IP-address:port＞ 当WWW请求达到服务器时，WWW服务器软件(Apache)用达到请求的IP地址和端口来发现匹配的虚拟主机配置，并用对应的虚拟服务器的配置来处理请求。因此可用不同的端口号来创建虚拟主机。
