mod_smacks: Disable resumption behavior on s2s Since resumption is not supported on s2s currently, there is no point in allocating resumption tokens. The code that removes entries from session_registry is only invoked for c2s sessions, thus enabling resumable smacks on s2s adds an entry that never goes away.
