当 Lua IPC 管道阻塞 OpenResty 或 Nginx 的事件循环
Echo Nginx ModuleYichun Zhang , 26 Aug 2011 (created 21 Jun 2011)
This module wraps lots of Nginx internal APIs for streaming input and output, parallel/sequential subrequests, timers and sleeping, as well as various meta data accessing.
Basically it provides various utilities that help testing and debugging of other modules by trivially emulating different kinds of faked subrequest locations.
