拒绝所有“直接”流量

我的服务器正在遭受严重攻击（可能是 DDOS，我不知道）。我检查了访问日志（为了便于理解，这个网站每天有 1000 名访问者，没什么特别的）：

我正在考虑暂时拒绝所有通过 htaccess 的直接流量（它只占我的流量的 %3%）。

我的问题是如何拒绝通过 .htaccess 的所有直接流量，这有帮助吗？

谢谢

答案1

我不会谈论是否.htaccess值得拒绝直接（无 Referer）请求，因为这可能或可能不值得，这取决于您的具体情况。

无论如何，下面是可以做到的。将以下内容放入.htaccess：

SetEnvIf Referer "^$" NO_REFERER
Order allow,deny
Allow from all
Deny from env=NO_REFERER

这应该允许所有 HTTP 请求，除了那些发送空白（或没有）Referer 标头的请求。

答案2

是的，您可以使用拒绝指令来拒绝特定 IP。作为更好的选择，您可以添加防火墙规则来阻止这些 IP 访问您的 Web 服务器。您必须确定自己在做什么。否则，您最终可能会阻止合法用户访问您的网站。
