1. Initial testing strategy is to move NGINX to port 80, and proxy everything to Apache on port 8090 — creating "Shims" for each IIAB app/service/playbook in *Section iii.* below.
Until "Native" NGINX is later implemented for that IIAB app/service/playbook — allowing it to move up to *Section ii.* below.
And potentially later moving it up to *Section i.* if its Apache support is dropped!
2. Supports "Native" NGINX ***AND*** Apache, a.k.a. "dual support" for legacy testing, which can be attempted by setting 'nginx_enabled: False' in /etc/iiab/local_vars.yml (if "Shims" from *Section iii.* below are preserved!)
3. Supports Apache but ***NOT*** NGINX, proxied by an NGINX "Shim" (see [roles/0-init/tasks/main.yml#L39-L49](../0-init/tasks/main.yml#L39-L49) for a list of those IIAB apps/services that auto-enable Apache)
