1207	Distinguish between 301 and 302 redirects when proxy_redirect off	stackoverflow.com/users/4514467/hugmanrique		"I'm creating an app that proxies it's content to imgur. When an image doesn't exist, it returns a 302 redirection to the 404 page which then throws a 404 (not catched by proxy_intercept_errors on; because a 302 is considered the first error by nginx). When people are using a phone, imgur throws a 301 redirection to m.imgur.com/route. Both examples are cached by my error_page when I would only want to catch the 302 redirection as an error. Here's my config:

server {
	listen 443 ssl http2;
	listen [::]:443 ssl http2;

	server_name domain.tld;

	ssl_certificate /path/a.pem;
	ssl_certificate_key /path/b.pem;

	root /path/web/;
	index index.html;

	error_page 301 302 307 501 502 503 400 404 = /notFound.html;

	location ~ \.(png|gif|jpg|gifv) {
		proxy_pass https://i.imgur.com;
		proxy_redirect off;
	        proxy_intercept_errors on;
	}
}

A proxy_redirect_type option would be neat for these cases. Even if I remove the 301 from the error_page, nginx still catches it and serves a default error page."	defect	closed	minor	1.11	nginx-core	1.9.x	invalid	proxy,redirections		Linux hugmanrique 4.4.0-38-generic #57-Ubuntu SMP Tue Sep 6 15:42:33 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/1.10.0 (Ubuntu)
