I'm having trouble understanding how things string together.

Correct me on these:

An App is what is presented on a web site. It could be a WordPress installation, it could be a directory structure of static html files, etc.

A Domain is an address like "google.com" or mysubdomain.myusername.opalstacked.com" (A external domain I control will not work at Opalstack until I specify the Opalstack Name Servers at my Domain Registrar.)

A Site Route associates one or more Domains with a web server (mine is opal3.opalstack.com). It also causes an App to be presented at the domain address. You call this setup "Site Routes." (The Edit page is titled "Site Details").

So. I'm moving files from Webfaction and want to test sites before changing my DSN info.

I should be able to do this by using a subdomain in the "Domain Info" section of a Site Routes entry. Yes?

But I read that I need a DNS A record for the subdomain. Supposedly, this will happen automagically when I specify a subdomain in a Site Routes entry. Which I have done.

But the subdomain does not work and I do not see any new records in the DNS Records page. (I would be happy to create the A record myself, if I had some guidance.)

Your thoughts will be appreciated!
