Description

Hi,

I added backup upstream server and proxy_next_upstream http_404 in conf if master upstream servers send 404 Nginx is trying from backup upstream. If backup upstream send 404, Nginx is starting loop on backup upstream and nonstop request same file.

I searched the problem and changed these codes in ngx_http_upstream.c and problem solved but I don't know exactly maybe wrong changes.

< if (ft_type == NGX_HTTP_UPSTREAM_FT_HTTP_404) {
< state = NGX_PEER_NEXT;
< } else {
< state = NGX_PEER_FAILED;
< }
---

state = NGX_PEER_FAILED;

Thanks.

Kind Regards

Semih Alev

Yes, thank you, it's known problem. Current implementation of backup servers doesn't work well with "proxy_next_upstream http_404".
