**Service:** TTB (Alcohol and Tobacco Tax and Trade Bureau) COLAs Online public registry
(`ttbonline.gov/colasonline`) — the public lookup for approved wine/beer/spirits label
applications.

**Probe 1 — the query/search FORM page itself, plain GET, no session:**
```
curl -I "https://ttbonline.gov/colasonline/publicSearchColasBasicQuery.do"
```
**HTTP 302**, `Location: https://ttbonline.gov/colasonline/oauth2/authorization/colas` —
even the "public" basic-search form requires bouncing through an OAuth2 authorization
flow before TTB will serve the search UI itself. This is a stricter gate than a typical
public registry homepage. The 302 response also sets a `JSESSIONID` cookie scoped to
`/colasonline` plus an F5 BIG-IP pool-affinity cookie (`BIGipServerCOLAS_PROD_POOL`) and
five separate `TS*`-prefixed cookies — the same F5/edge-session cookie family seen in
front of the search form itself (Probe 2), meaning a session is already being established
by the load balancer before any OAuth redirect is even followed.

**Probe 2 — the process/submit endpoint, GET with no params, no session:**
```
curl "https://ttbonline.gov/colasonline/publicSearchColasBasicProcess.do"
```
**HTTP 200**, 39,060 bytes, `charset=ISO-8859-1`, title "Public COLA Registry Search" — it
serves the full basic-search HTML form (meant to be reached via POST after a real search),
not an error and not a results page.

**Probe 3 — the same process endpoint, GET with search query-string parameters attached
(`searchCriteria.brandName=BUDWEISER&action=search`) instead of the POST body the app
expects:** **HTTP 200**, 39,233 bytes — still just the blank search form (title and shell
byte-for-byte the same as Probe 2's); the brand-name parameter is silently ignored rather
than producing results or a 400/405. A GET-only client cannot retrieve COLA search
results from this endpoint at all: it needs either the OAuth2-gated query page's session
or a real POST, neither of which this lane sends (no POST to a third-party target is sent
under any circumstance here).

How observed: 2026-10-05T09:31:52Z–09:32:05Z, three live `curl`/`curl -I` **GETs only**
against `ttbonline.gov`, `-m 30 --max-filesize 20000000`, no key, default UA. No form
submission (POST) was attempted.
