I am trying to reverse proxy my website and modify the content. To do so, I compiled nginx with sub_filter. It now accepts the sub_filter directive, but it does not work somehow.
server {
listen 8080;
server_name www.xxx.com;
access_log /var/log/nginx/www.goparts.access.log main;
error_log /var/log/nginx/www.goparts.error.log;
root /usr/share/nginx/html;
index index.html index.htm;
## send request back to apache1 ##
location / {
sub_filter <title> '<title>test</title>';
sub_filter_once on;
proxy_pass http://www.google.fr;
proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
proxy_redirect off;
proxy_buffering off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
Please help me

Check if the upstream source has gzip turned on, if so you need
proxy_set_header Accept-Encoding "";
so the whole thing would be something like
location / {
proxy_set_header Accept-Encoding "";
proxy_pass http://upstream.site/;
sub_filter_types text/css;
sub_filter_once off;
sub_filter .upstream.site special.our.domain;
}
