snutt-proxy

Reverse proxy for SNU sugang syllabus pages (강의계획서). sugang.snu.ac.kr redirects to its main page unless Referer is under *.snu.ac.kr, so this proxy forwards requests with the required Referer attached, using the same paths as the upstream so the page works without HTML rewriting.

Routes

• GET/POST /sugang/cc/{action}: only cc1XX(ajax)?.action
• GET /kor/**, /adm/**: static assets. Paths with a .. segment are 404. 2xx and 304 responses without Cache-Control get Cache-Control: public, max-age=86400.
• GET /healthz: not written to the access log

Other paths and actions are 404. GET routes also accept HEAD. A listed path with another method is 405. /kor and /adm redirect to /kor/ and /adm/. Cookies are stripped in both directions. A request whose client disconnects before the upstream responds is logged with status 499.
