Scenario: "Hangzhou": The web server one-second delay that never happens

Level: Medium

Type: Fix

Tags: nginx  

Access: Email

Description: West Lake Quotes is a staging market-data gateway. GET /v1/quote on port :80 should wait about one second and then return the matching engine payload. The engine itself listens on 127.0.0.1:5000 and must stay fast.

After last Thursday's nginx change the JSON is still correct, but the courtesy delay never happens — quotes come back in a few milliseconds. The mobile QA build depends on that wait (spinner and retry logic).

There is a short handover note in /home/admin/HANDOVER.txt. Do not take the gateway off port 80, and do not add latency to the engine.

Root (sudo) Access: True

Test: curl -s http://127.0.0.1/v1/quote returns the engine JSON (fields westlake and WLTEA) and the request takes roughly one second.

curl -s http://127.0.0.1:5000/v1/quote still returns the same payload immediately.

The "Check My Solution" button runs the script /home/admin/agent/check.sh, which you can see and execute.

Time to Solve: 20 minutes.
