The SSL context to use for connections using TLS.
boost::optional< asio::ssl::context > ssl_ctx {};
If a non-empty value is provided, all connections created by the pool will use the passed context when using TLS. This allows setting TLS options to pool-created connections.
If an empty value is passed (the default) and the connections require TLS, an internal SSL context with suitable options will be created by the pool.
