EJ Schmidt asks for the best approach to host a subfolder (`/subfolder/`) with tens of thousands of dynamic pages on an external server, while the main domain stays on HubSpot.

Jennifer Nixon explained that this requires a reverse proxy setup, contingent on the external server's configuration and requiring HubSpot Enterprise. She questioned the approach, suggesting HubDB might be suitable (though EJ cited limitations/performance issues) and raised concerns about the SEO effectiveness of so many pages.
