我的网站托管在AWS上，我使用SEMRush来跟踪任何服务器和编程问题。
我的SEMRush在运行时发现了这个错误。
2个子域不支持HSTS。

因此我把下面的代码来解决这个问题

<IfModule mod_headers.c>
        <If "%{REQUEST_SCHEME} == 'https' || %{HTTP:X-Forwarded-Proto} == 'https'">
            Header set Strict-Transport-Security "max-age=31536000"
        </If>
    </IfModule>

现在解决了1个错误，但仍有一个子域具有相同的错误。

正如你所看到的，rosterelf.com仍然不支持HSTS。
此外，我在htaccess中将非www重定向到www，这就是我的.htaccess文件的样子。

<IfModule mod_rewrite.c>

    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    <IfModule mod_headers.c>
        <If "%{REQUEST_SCHEME} == 'https' || %{HTTP:X-Forwarded-Proto} == 'https'">
            Header set Strict-Transport-Security "max-age=31536000"
        </If>
    </IfModule>

    RewriteEngine On

我需要把下面的代码

<IfModule mod_headers.c>
        <If "%{REQUEST_SCHEME} == 'https' || %{HTTP:X-Forwarded-Proto} == 'https'">
            Header set Strict-Transport-Security "max-age=31536000"
        </If>
    </IfModule>

在<IfModule mod_rewrite.c>条件之外？我应该怎么做来解决这个问题？
有人能给我指路吗。
谢谢
