code: def connection_from_url(self, url, pool_kwargs=None):
          
          u = parse_url(url)
          return self.connection_from_host(u.host, port=u.port, scheme=u.scheme,

docs: Similar to :func:`urllib3.connectionpool.connection_from_url`.
  
          If ``pool_kwargs`` is not provided and a new pool needs to be
          constructed, ``self.connection_pool_kw`` is used to initialize
          the :class:`urllib3.connectionpool.ConnectionPool`. If ``pool_kwargs``
          is provided, it is used instead. Note that if a new pool does not
          need to be created for the request, the provided ``pool_kwargs`` are
          not used.
