Every site that is defined in the CMS has its own context, which includes a base site ID, language properties, and currency properties. The context also defines how these attributes are persisted in the URL.
You can configure your application by defining static
context properties, as described in Static Multi-Site Configuration. However, the recommended approach is to not configure the
context property, and instead to allow Spartacus to automatically determine the context based on the URL patterns of your sites, as defined in the CMS. For more information, see Automatic Multi-Site Configuration.
