我如何检查一下是否读到该网页的URL是原来的URL,还是如果它有CNAME记录的话。
例如,我有一个网站domain.com
。 用户可以设立CNAME,将www.otherdomain.com
连接到我们的网站domain.com
。
从我们的服务器角度看,我如何发现,如果进入该网页的URL是实际的(domain.com
)还是国家空间活动委员会(www.otherdomain.com
)?

如果你重新检查URLs,可在PHP中使用_SERVER[ HTTP_HOST]
。 The s the requestedshop from the URL (eg http://otherdomain.com/blah.php 服务器将贴上<代码>otherdomain.com。 $_SERVER[SERVER_NAME]
is the configured Servicename in the httpd.conf.
