We use Nginx as a proxy to our internal API server. Our API server misbehaves sometimes and times out. Normally, when this happens, Nginx issues a 504 bad gateway. However, if the request happens to be a POST request, it appears that NGINX issues a 404 Page Not Found error." defect closed minor nginx-module 1.4.x worksforme Linux testing-1 3.13.0-46-generic #79-Ubuntu SMP Tue Mar 10 20:06:50 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux "nginx version: nginx/1.4.6 (Ubuntu) "
