hey guys,
So I had 3 sites configured to use caching on my nginx box (tried with
.50, 52 and 53 build) however of the three websites kept redirecting
me to the first site that I was doing caching for.
Example Sites:
0.0.0.1
0.0.0.2
0.0.0.3
HTTP config very similar to this only each utilize a different
"listen" ip address and each site has a different Backend 'Origin" ip:
# HTTP LB
upstream LB_HTTP_0.0.0.1 {
server x.x.x.x:80;
}
server {
listen 0.0.0.1:80;
server_name website_0.0.0.1;
access_log /var/log/nginx/any.website_0.0.0.1.access_log main;
error_log /var/log/nginx/any.website_0.0.0.1.error_log info;
error_page 404 /404.html;
location = /404.html {
root html;
}
error_page 404 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location / {
proxy_intercept_errors on;
proxy_pass http://LB_HTTP_0.0.0.1;
proxy_cache one;
proxy_cache_key backend$request_uri;
proxy_cache_valid 200 1h;
proxy_cache_valid 404 5m;
proxy_cache_use_stale error timeout invalid_header;
}
}
When browsing to 0.0.0.1, everything was fine
going to 0.0.0.2 or 0.0.0.3 or any other ip for that matter in the
same class C "/24" it would redirect you to the 0.0.0.1 config which
would then proxy-pass the data back to the origin belonging to the
0.0.0.1 config
Anyone seen this issue at all?
Once i commented all proxy_cache and restarted nginx, problem went away.
Note that i even tried deleting /etc/nginx-cache/* and recreating
it... did not help
Thanks,
