purge returns 404

[mostafahussein]

This may not an issue with the purge module itself, but i am looking for an explanation. My settings are quite simple. Just as the example but with a different cache key and I have tried the same example but still getting same result.

In vhost.conf

  location ~ /purge(/.*) {
            proxy_cache_purge  cache_proxy $scheme$request_method$host$request_uri;
  }

In nginx.conf

 proxy_cache_path /usr/local/nginx/proxy levels=1:2 keys_zone=cache_proxy:15m inactive=4h max_size=1000m use_temp_path=off;
    proxy_cache_key $scheme$request_method$host$request_uri;
    proxy_cache_use_stale error timeout invalid_header updating http_500 http_502 http_503 http_504 http_403 http_404;
    proxy_cache_valid  any 1m;

When I try to purge the HTTP status is 404. I always make sure that X-Proxy-Status: HIT when requesting something like: curl -I http://example.com/test.php and trying to purge it with curl -I http://example.com/purge/test.php -XPURGE

Could example to me what is the wrong with my configuration ?
I am using nginx 10.x with this module and also tried the original one but still same result

• proxy_cache_purge collision key?
  • These sections are in different vhost?
• Are you sure that the key inside will be the same vhost (server) and the level server (http) above?

  location ~ /purge(/.*) {
    # proxy_cache_purge  cache_proxy "$scheme$request_method$host$request_uri";
    default_type text/plain; # not "application/octet-stream"
    return 200 "$scheme$request_method$host$request_uri";
  }

… {
  proxy_cache_path …
  proxy_cache_key "$scheme$request_method$host$request_uri";
  default_type text/plain; # not "application/octet-stream"
  return 200 "$scheme$request_method$host$request_uri";
}

I have nginx.conf with include /path/to/vhosts/*.conf where i keep a vhost - server module - for each site.
I have proxy settings under http module in nginx.conf

#nginx.conf
proxy_cache_path /usr/local/nginx/proxy/domain.com levels=1:2 keys_zone=domain.com_cache:15m inactive=4h max_size=1000m use_temp_path=off;
proxy_cache_key $scheme$request_method$host$request_uri;
proxy_cache_use_stale error timeout invalid_header updating http_500 http_502 http_503 http_504 http_403 http_404;
proxy_cache_valid  any 1m;

#domain.com.conf
    location / {
        proxy_pass http://apache_reverse;
        proxy_cache domain.com_cache;
        add_header X-Proxy-Cache $upstream_cache_status;
        # 2 rules to dedicate the no caching rule for logged in users.
        proxy_cache_bypass $nocache; # Do not cache the response.
        proxy_no_cache $nocache; # Do not serve response from cache.
    }

    location ~ /purge(/.*) {
        #proxy_cache_purge arabturkey_cache $scheme$request_method$host$request_uri;
        default_type text/plain; # not "application/octet-stream"
        return 200 "$scheme$request_method$host$request_uri";
    }

$ curl -L domain.com/purge/
httpsGETdomain.com/purge/

I have the same issue on nginx-1.10.0
nginx.conf

location / {
    proxy_pass http://127.0.0.1:8000;
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    proxy_cache tmpcache;
    proxy_cache_key    $uri$is_args$args;
    proxy_cache_valid 200 6M;
    proxy_ignore_headers Cache-Control;
    proxy_ignore_headers Set-Cookie;
    proxy_hide_header Set-Cookie;
    add_header X-Cached $upstream_cache_status;

    proxy_cache_purge  PURGE from 127.0.0.1;

    etag on;
}

I have cache file with key

...
KEY: /api/nsi/directory-items/397/
...

But when I make PURGE request on this url nginx returns 404

127.0.0.1 - - [05/May/2017:16:32:16 +0300] "PURGE /api/nsi/directory-items/397/ HTTP/1.1" 404 142 "-" "python-requests/2.13.0" "-"

I can't reproduce it. Can I see the your debug log?

[davydovsky]

@torden
I've reinstalled nginx and the ngx_cache_purge module with the latest changes from master.
Now it works as expected.

[torden]

@davydovsky
sounds good!

@mostafahussein
Could you trying to reproduce base on the changes from master?
if there are still problems, Can I see the your debug log ?
