Thanks for reminding me about the filter-mapping; I'd forgotten to uncomment it when I'd stuck the filter configuration onto the "guinea pig" server. Once I did that, and restarted, Firefox started showing:

Strict-Transport-Security
        max-age=0
X-Content-Type-Options
        nosniff
X-Frame-Options
        SAMEORIGIN

Wait a second. Could I have . . . HOLY [redacted], I *WAS* that [redacted] stupid! When I was pre-staging the customer's update to 9.0.106, I'd uncommented the filter configuration and added the anti-clickjacking parameters, but I'd forgotten to uncomment the filter-mapping!

But I still do have a question:

My filter configuration looks like this:
<filter> <filter-name>httpHeaderSecurity</filter-name> <filter-class>org.apache.catalina.filters.HttpHeaderSecurityFilter</filter-class> <init-param> <param-name>antiClickJackingOption</param-name> <param-value>SAMEORIGIN</param-value> </init-param> <async-supported>true</async-supported> </filter>

If I'm adding more parameters, do I put them within the same <init-param> tags, or a separate pair of <init-param> tags?
