Upstream keepalive: keepalive_requests directive. The directive configures maximum number of requests allowed on a connection kept in the cache. Once a connection reaches the number of requests configured, it is no longer saved to the cache. The default is 100. Much like keepalive_requests for client connections, this is mostly a safeguard to make sure connections are closed periodically and the memory allocated from the connection pool is freed.
