# nginx reverse proxy for the LPRA server.
|
|
# TLS is terminated here; the Go server listens on 127.0.0.1:8091.
|
|
#
|
|
# Put this in /etc/nginx/sites-available/lp_agent and symlink it into
|
|
# sites-enabled, then: sudo nginx -t && sudo systemctl reload nginx
|
|
#
|
|
# Everything (agent + browser terminal) is plain HTTP long-polling, so NO
|
|
# WebSocket config is needed. The two settings that matter:
|
|
# - proxy_buffering off -> deliver long-poll responses immediately
|
|
# - proxy_read_timeout 120s -> longer than the 25s long-poll hold
|
|
#
|
|
# NOTE: proxy_pass MUST start with "http://". A bare "proxy_pass 127.0.0.1:8091;"
|
|
# causes nginx error: [emerg] invalid URL prefix.
