## HKEX's once-public `hkexwidget` JSON quote endpoint is WAF-gated for plain HTTP clients

```
GET https://www1.hkex.com.hk/hkexwidget/data/getequityquote?sym=700&token=&lang=eng&qid=1
```
(symbol 700 = Tencent, a real, heavily-traded HKEX listing) → HTTP **403**, `content-type:
text/html;charset=UTF-8`, a generic Java servlet "Error report" page (Tomcat-shaped), plus
`Set-Cookie: TS01facf52=...` and `TS0164a861=...` — the `TS0` cookie-name prefix is the signature of
an Akamai Bot Manager "sensor" challenge, set on the **same** 403 response, not after a prior
successful handshake.

Adding `Referer: https://www.hkex.com.hk/` (the obvious same-site referer a browser would send) makes
no difference — still 403, identical page.

Re-running with a deliberately invalid symbol (`sym=999999`) gives the **same** 403/Tomcat response —
so this endpoint no longer distinguishes "valid symbol, forbidden client" from "invalid symbol" at
all; every plain HTTP request is rejected before the application logic that would validate the symbol
ever runs. A URL shape that is widely documented/screenshotted online as a "keyless JSON quote
endpoint" is, as observed today, not reachable by a plain HTTP client under any header combination
this lane tried.

The response still carries the API's own `Allow: OPTIONS, POST, DELETE, PUT, GET` and
`Access-Control-Allow-Origin: *` headers even on the 403 — the CORS and method-negotiation layer of the
real application is visible right through the WAF block, which is specific to this endpoint's own
server configuration rather than a blanket edge rule for the whole `hkex.com.hk` domain (a plain page
load of the main HKEX site works normally). That split — CORS headers present, content blocked —
suggests the WAF sits in front of the application server rather than replacing it.

How observed: 2026-10-05 ~07:37Z, curl 8.x, with a descriptive contact User-Agent and with/without a
same-site Referer header, from this machine.
