About this task

In addition to loading JWKs from each configured OIDC provider's jwks_uri endpoint when the HTTP task starts and restarts, the JWK cache management thread tracks the JWK expiration time returned by providers in their cache-control response headers and refreshes providers' JWKs before they expire. Providers that do not return cache-control headers are refreshed every 15 minutes by default.

The JWK cache management thread also checks the cache for long-expired JWKs and removes them to prevent the cache from growing out of control.
