# ol.clave.acme.impl.directory-cache

Global directory cache with TTL for ACME directory responses.

ACME directories rarely change, so caching them avoids unnecessary network
requests for long-running servers managing many domains.

The cache is keyed by directory URL with a 12-hour default TTL.
Stale entries remain until replaced (no background cleanup).

## default-ttl-ms

Default TTL of 12 hours in milliseconds.
