Ok, maybe not so beautiful solution but upstream can be used with one server
makred as down.
http {
upstream backend-jail {
server 0.0.0.0 down;
}
server {
listen 80;
underscores_in_headers on;
recursive_error_pages on;
error_page 597 = @jail;
location / {
I'm using ngnix as proxy server. There is a situation when backend server is
down and I know about it. Thus I'm adding 'Check-Cache' header to request
and what I want to do is get the file when it is in cache, and when it is
not just return error page. I don't want to pass the request to the
backen
