Can somebody confirm that proxy_cache_purge is working with nginx/0.8.34.

I have this config and cannot get it to delete anything from the cache, I just get a 404:

[code]
location / {
proxy_pass http://127.0.0.1:8000;
proxy_cache tmpcache;
proxy_cache_key "$scheme://$host$request_uri";
}

location ~ /purge(/.*) {
allow 127.0.0.1;
deny all;
proxy_cache_purge tmpcache "$scheme://$host$1";
}
[/code]

Thank you.
