Nginx cache filename

[Daniel Biazus]

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
