For subfolder installs (e.g. `example.com/forum`), `FinalDestination` was ignori…ng all URLs on the parent domain instead of just URLs under the subfolder path. ### Problem When Discourse is installed in a subfolder like `https://tecnoblog.net/comunidade/`, attempting to onebox/fetch URLs like `https://tecnoblog.net/noticias/...` (WordPress blog on same domain) would fail because FinalDestination immediately returned without making any HTTP request. ### Cause - `Discourse.base_url_no_prefix` returns just `https://tecnoblog.net` (no path) - Only hostnames were stored in the ignored list - Any URL on `tecnoblog.net` matched and was ignored ### Fix - Use `Discourse.base_url` which includes the subfolder path - Store both hostname and path in the ignored list - Check both hostname AND path prefix when determining if a URL should be ignored ### Security SSRF protection is unaffected - it runs after the ignored check, so URLs that are no longer ignored still go through IP validation. Added a test to verify this.
