比如，一个代理服务器可能会缓冲响应而造成延迟。

For example, a proxy server may be buffering the response and cause latency.

也就是说，目前请求在到达应用程序服务器之前，必须通过两个组件(代理和odr)，因而增加了延迟。

That is, the requests must now pass through two components (the proxy and ODR) before reaching the application server, which does increase latency.

另外，代理服务器可能会缓冲未加密的HTTP响应，这将会对HTTP响应流带来不可估计的延迟。

Additionally, proxy servers may also buffer unencrypted HTTP responses, thereby introducing unpredictable latency during HTTP response streaming.
