我试图在(httpd.conf)中理解HostnameLookups的含义。我也对这个指令的目标感兴趣。
谢谢Alessandro

根据“手册”：
This directive enables DNS lookups so that host names can be logged
(and passed to CGIs/SSIs in REMOTE_HOST). The value Double refers to
doing double-reverse DNS lookup. That is, after a reverse lookup is
performed, a forward lookup is then performed on that result. At
least one of the IP addresses in the forward lookup must match the
original address. (In "tcpwrappers" terminology this is called PARANOID.)页面原文内容由Server Fault提供。腾讯云小微IT领域专用引擎提供翻译支持
