Domain Types
Single Domain
In most cases, you will probably only need to use a single domain, such as example.com. when we have multiple services, we can use a subdomain like app.example.com. swag is configured for use with a single domain by default
Sub-Domains
Sub domains are a way to host multiple applications or services from the same domain. Such as app.example.com.
While sub folders such as example.com/app can be used, they can require extra configuration. Most apps support Sub-Domains by default. These are great for building a community around the same name, such as forum.example.com and blog.example.com with example.com being your primary website.
Multiple Domains
You can use multiole domains like example1.com and example2.com. swag needs to be configured to create an SSL certificate for both, then individual proxy configs need to be updated to show the full domain name instead of the asterisks.
