CentOS 6.8
Apache 2.2
我有两个网站 (moodle 和 mahara) 在该服务器上运行。出于某种原因，其中一个 (moodle) 的 ssllabs 测试结果正常，但对于 mahara 网站，我收到此警告：
Strict Transport Security (HSTS) Invalid Server provided more than one HSTS header
这是处理它们两个的 ssl.conf 文件：

除了 moodle 虚拟主机有一些关于 winbind 和 ntlm 的额外信息外，我很确定它们是相同的。
有人知道为什么我可能会收到针对其中一个虚拟主机的警告，而另一个却没有收到？
谢谢
答案1
Strict-Transport-Security如果使用 HTTPS，Mahara 会自行设置标头：
header('X-Permitted-Cross-Domain-Policies: master-only');
if (is_https()) {
header('Strict-Transport-Security: max-age=63072000');
只需从 Apache 配置中删除该 vhost 的标头即可。
