The Custom Locations tab rendered every location fully expanded, which
becomes unusable once a host has more than a handful of them. Each row is
now a collapsible card showing its path and forward target, collapsed by
default, with the Add Location button moved to the top so it stays
reachable without scrolling to the end of the list.
A filter appears once there are five or more locations and matches on the
path as well as the forward scheme, host and port.
New locations are still appended to the end of the list, so the generated
nginx config is unchanged.
Also fixes two existing issues in this component: the per-location inputs
shared the same DOM ids across rows, and the advanced-config toggle state
was keyed by array index, so removing a location moved it onto the wrong
row.
When Nginx is behind another proxy server (like CloudFlare or AWS ALB), the force-SSL
feature can cause redirect loops because Nginx sees the connection as plain HTTP
while SSL is already handled upstream. This adds a new boolean option to trust
the X-Forwarded-Proto header from upstream proxies.
Changes:
- Add `trust_forwarded_proto` column to proxy_host table (migration)
- Update model and API schema to support the new boolean field
- Modify force-ssl Nginx template to check X-Forwarded-Proto/X-Forwarded-Scheme
- Add map directives in nginx.conf to validate and sanitize forwarded headers
- Add advanced option toggle in frontend UI with i18n support (EN/ZH)
- Set proxy headers from validated map variables instead of $scheme
This allows administrators to control SSL redirect behavior when Nginx is deployed
behind a TLS-terminating proxy.
