Subject: Simplify keep-alive action. Now the interval is based on
 session_lifetime, which means it's executed only if needed for session
 keeping (reset interval on every action).

Temporarily remove check-recent request, it will be replaced by new global system refresh request in future.
Use keep_alive setting as auto-refresh request interval (allow no-refresh mode)
