against each other; however, they got settled down in a minute or
two, and the game began.  Alice thought she had never seen such a
curious croquet-ground in her life; it was all ridges and
furrows; the balls were live hedgehogs, the mallets live
flamingoes, and the soldiers had to double themselves up and to
stand on their hands and feet, to make the arches.

    Applications should avoid creating many connection pools as doing so
    prevents connection reuse. Each connection pool holds its own set of
    connections alive so applications that have many pools also risk exhausting
    memory!

    The best practice in OkHttp 3 is to create a single OkHttpClient instance
