Nginx HTTP Server - Fourth Edition

open_file_cache_min_uses

Context: http, server, and location

By default, entries in the open_file_cache are cleared after a period of inactivity (60 seconds, by default). If there is activity though, you can prevent Nginx from removing the cache entry. This directive defines the number of times an entry must be accessed in order to be eligible for protection:

open_file_cache_min_uses 3; 

If the cache entry is accessed more than three times, it becomes permanently active and is not removed until Nginx decides to clear out older entries to free up some space.

Syntax: Numeric value

Default value: 1
