Following it, `GET /gpr/` → 200, `text/html`, 41,817 bytes — the real landing page (a JavaScript search app shell).\n\n`GET /gpr/search/service.html` (the search endpoint path referenced by the portal's own JS) → **405**, `content-length: 0`, `text/html; charset=UTF-8` — a completely empty body, and critically **no `Allow` header** naming which methods are accepted, so a client cannot even learn \"try POST\" from the response itself. Response headers show an F5 Distributed Cloud (Volterra) edge (`server: volt-adc`, `x-volterra-location: b-sv10-sjc`) and **two** `TS*`-prefixed session cookies (F5 BIG-IP ASM tokens, `HttpOnly`, `Secure`, `SameSite=Strict`) set on this 405 response — the edge is issuing anti-bot session state even on a refused request.\n\nA guessed JSON endpoint, `GET /gpr/search/catalogue.json`, → **404**, `text/html; charset=UTF-8`, 1,556 bytes, G-Portal's own styled 404 page (not the edge's error page) — so paths under `/gpr/` that don't exist get the application's 404, while the one path that does exist but wants a different method gets the edge's bare 405.\n\n## Auth\nNot reached; whatever auth the real search call uses is behind the 405 wall.\n\n## Rate limits\nNot observed.\n\n## Freshness\nNot observable.\n\n## Known gaps\n- No GET-reachable path returned structured (JSON/XML) satellite data in this session.
