Overview
Promino serves your published site from the edge for speed and reliability, with HTTPS handled for you. You don’t manage certificates or servers - connect your domain and Promino takes care of secure, fast delivery.
HTTPS
Traffic to your site is encrypted over HTTPS. When you connect a custom domain, requests to your promino.app subdomain are redirected to your custom domain so visitors and search engines see a single secure address.
Edge delivery and caching
- Pages are cached at the edge and refreshed when you publish, so visitors get fast responses and you still see updates quickly.
- Static assets such as images and scripts are cached aggressively for performance.
When you publish
Publishing a page refreshes the cached version of that page so your changes go live promptly. See Publish your site for the full flow.
If your site is offline
If a site’s subscription is inactive, the site is taken offline and visitors see an unavailable message instead of your content. Keeping your billing active keeps your site served.
