Nginx fastcgi_cache_key Howto

Nginx fastcgi_cache_key Howto:

syntax: fastcgi_cache_key line

default: none

context: http, server, location

The directive sets the key for caching, for example:

  fastcgi_cache_key localhost:9000$request_uri;

Be advised that a HEAD request can cause an empty response to be cached & later be distributed to GET requests, avoid this by having $request_method in the cache key.
