📚 Description

This PR adds a check to determine if the provided baseUrl config entry is an external or internal API route. This check is done by:

• 1. If the baseURL includes a host
  • If not, then the baseURL is assumed to be an internal Nuxt route
• 2. if the baseURL host matches the host of the current event.req
  • If a host was added that matches the URL of the application, then requests are handled as internal requests

📝 Checklist

• I have linked an issue or discussion.
• I have added tests (if possible).
• I have updated the documentation accordingly.
