she stood watching them, and he checked himself suddenly:  the
others looked round also, and all of them bowed low.

  `Would you tell me,' said Alice, a little timidly, `why you are
painting those roses?'

  Five and Seven said nothing, but looked at Two.  Two began in a
low voice, `Why the fact is, you see, Miss, this here ought to
have been a RED rose-tree, and we put a white one in by mistake;

(like HTTP/2).

URLs that share the same address may also share the same underlying TCP socket connection. Sharing a connection has substantial performance benefits: lower latency, higher throughput (due to [TCP slow start](https://www.igvita.com/2011/10/20/faster-web-vs-tcp-slow-start/)) and conserved battery. OkHttp uses a [ConnectionPool](https://square.github.io/okhttp/5.x/okhttp/okhttp3/-connection-pool/) that automatically reuses HTTP/1.x connections and multiplexes HTTP/2 connections....
