+### Proxy configuration in front of Team Edition
+
+If you place your own reverse proxy in front of Team Edition instead of the bundled `web-proxy`, it must forward the following headers so the backend can resolve the correct public origin.
+
+The backend looks for the public origin in this order (first non-empty wins):
+
+- `Origin` — public URL the client used (`scheme://host[:port]`).
+- `X-Origin` — fallback when `Origin` is absent.
+- `Referer` — last-resort fallback.
+- `X-Forwarded-Scheme` — original scheme (`http` / `https`).
+- `X-Forwarded-Proto` — fallback for `X-Forwarded-Scheme` (`http` / `https`).
+- `X-Forwarded-Host` — original host. If both the scheme and host above are set, they override `Origin` / `X-Origin` / `Referer`.
+- `X-Forwarded-Port` — original port (only needed if it differs from 80/443).
