永远的彗星技术吗？ [英] Forever Frame comet technique?

问题描述

有人可以向我解释永久框技术如何工作吗？一个代码示例太棒了！我遍历了所有我可以在Google上找到的资料，但我仍然对它的工作原理一无所知。

Can someone please explain me how the "Forever Frame" technique works ? A code example would be awesome! I went through all the material i could find in Google but i still don`t have much of an idea how it works.

推荐答案

简而言之，它使用块编码，这是HTTP / 1.1的功能，旨在完全不同的目的，但是允许服务器无限期地维护与客户端的连接，并随意向客户端发送其他数据。

In short, it uses "chunked encoding", a feature of HTTP/1.1 intended for an entirely different purpose, but which allows the server to maintain a connection to the client indefinitely, sending additional data to the client at will.

如迪伦所说：

此技术的延迟很短，因为它通过重新使用单个长期连接来避免HTTP和TCP / IP的建立和拆除。

This technique is very low-latency because it avoids HTTP and TCP/IP set-up and tear-down by reusing a single long-lived connection.
