You may use the md5 function in order to get the cache file on filesystem, Ex:
If you use the cache key "$host$uri$is_args$args" and the cache base path is /var/cache/nginx/ and cache has 2 levels (levels=1:2) Considering the URL "http://example.com/static/test.png"; The cache file name will be /var/cache/nginx/5/43/6e281642dfbf0b9ebf4cfb30142ab435 Based on: echo -n 'example.com/static/test.png' | md5sum 6e281642dfbf0b9ebf4cfb30142ab435 First level = 5 Second level = 43 Filename = 6e281642dfbf0b9ebf4cfb30142ab435 Hope it helps On Wed, Jan 20, 2016 at 6:05 AM, Tigran Bayburtsyan < [email protected]> wrote: > Hi All > > I’m doing centralized service for clearing our servers Nginx cache for > specific files, but I can’t find the algorithm how Nginx making cache file > based on request and cache_key. > > The only thing in documentation is > http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_cache_path > > How can I get cache file path for this static file > http://example.com/static/test.png ? > > > > Thanks > > _______________________________________________ > nginx-devel mailing list > [email protected] > http://mailman.nginx.org/mailman/listinfo/nginx-devel > -- Daniel Biazus infrastructure Engineering Azion Technologies Porto Alegre, Brasil +55 51 3012 3005 | +55 51 82279032 Miami, USA +1 305 704 8816 Quaisquer informações contidas neste e-mail e anexos podem ser confidenciais e privilegiadas, protegidas por sigilo legal.
