Proxy_cache_purge clear Nginx Cache return 404

Today debug Nginx A third-party purge cache module Proxy_cache_purge.

During debugging, the cache already has data but it is not clear that the return is always 404.

The last check for a long time, the reason for people three black lines ah.

Original configuration at the beginning

Put in

After that.

Change the order OK.

However, the configuration was configured on the official website. The official website example is as follows:

Sample configuration (separate location syntax)

http {    proxy_cache_path  /tmp/cache  keys_zone=tmpcache:10m;    server {        location / {            proxy_pass         http://127.0.0.1:8000;            proxy_cache        tmpcache;            proxy_cache_key    $uri$is_args$args;        }        location ~ /purge(/.*) {            allow              127.0.0.1;            deny               all;            proxy_cache_purge  tmpcache $1$is_args$args;        }    }}


我们使用的nginx和清除插件是被公司改过的，不知道是不是这个原因。
总之吧，这种限制真是。。。。
