，而 Android 2.3 及以上使用 HttpUrlConnection 的方案。这是因为在 Android 2.3 以下时，HttpUrlConnection 并不完善，有很多 bug 存在。因此在

Android 来说默认情况下 HttpURLConnection 和 HttpClient 都开启了 keep-alive。只是 2.2 之前 HttpURLConnection 存在影响连接池的 Bug，具体可见：

HttpStack.java：处理HTTP请求，返回请求结果。目前Volley中有基于 HttpURLConnection 的 HurlStack 和 基于 Apache HttpClient 的HttpClientStack。
