Detailed Description

A simple cache holding one ripple::LedgerHeader to reduce DB lookups.

Used internally by backend implementations. When a ledger header is fetched via FetchLedgerBySeq (often triggered by RPC commands), the result can be stored here. Subsequent requests for the same ledger sequence can proceed to retrieve the header from this cache, avoiding unnecessary database reads and improving performance.
