pcre_cache_ttl

pcre_cache_ttl — set the maximum TTL for the ec_pcre_compile cache

pcre_cache_size = 300

pcre_cache_size and pcre_cache_ttl together set the maximum size and TTL of the ec_pcre_compile cache. This cache is used by sieve, sievelib, the bounce_classifier code and the vctx_filter module to cache compiled regular expressions. It should not normally be necessary to modify these values.

The default value is 300.

pcre_cache_ttl is valid in the global scope.
