match_cache_life — set the maximum number of seconds that the match cache will be valid
match_cache_life = 0
match_cache_life determines the maximum validity for cache entries in the match cache. With a default match_cache_life of
0, cache entries will be kept for as long as they are still usable and the cache size hasn't been exceeded. Normally it is not necessary to set this option to a value other than
match_cache_life is valid in the global scope.
