There are four in-memory caches as follows. They are not configurable.

■   re-signed certificate cache
■   URL category cache
■   revocation certificate cache
■   session resumption cache

Cache Persistence

Caches are maintained for Internet lookups such as URL categorization and certificate revocation checks using OCSP or CRL for faster subsequent lookups. The cache persistence feature allows the information to be saved on the GigaVUE node in the control card’s persistent storage so that it can be retrieved in case of reboots. This allows the GigaSMART card to start with the information learned earlier. This feature is enabled by default and can be disabled if needed.

You can search for specific entries in the caches, clear them, and display a summary of the records.
