Is this a true statement?

If KeepAlive is set to off, it doesn't matter what KeepAliveTimeout is defined to be because KeepAlive is off.

So I'm just confirming I understand this correctly. KeepAliveTimeout bares no relevance when KeepAlive is off.

Correct - with KeepAlive off, connections will be closed immediately after the request is served, which means that the KeepAliveTimeout setting on how long to keep connections open for new requests is irrelevant.

As an aside, for the vast majority of web server workloads, allowing HTTP keepalive is a very good thing from a performance perspective for both the client and the server - turn it off with caution.
