As you've seen, "if" inside "location" does probably not do what you
want it to.

The usual nginx way is to have multiple server{} blocks with different
server_name values.

http://nginx.org/en/docs/http/server_names.html has details.

In your "not-www" server block, include the "location = /" block with
the try_files. In your "www" server block, don't.

If you can enumerate your server names, that would be ideal. If not,
perhaps you can use one "server_name www.*" and have the other be the
default. And failing that, then perhaps something like

  server_name ~^(www\.)(?<domain>.+)$;

and

  server_name ~^(?<vanity>[^.]+)\.(?<domain>.+)$;

(which would give you $domain, as well as $vanity) could work.

Or possibly, avoid all that and just set $vanity as the first bit of
$host or $http_host, and make sure that /landing-cache/vanity:www.html
does not exist.

It probably depends on what other differences you want between the
various server_name configurations.

Good luck with it,
