What is libnginx-mod-http-echo
libnginx-mod-http-echo is:
Echo 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.
People will also find it useful in real-world applications that need to:
- Serve static contents directly from memory.
- Wrap the upstream response with custom header and footer (kinda like the addition module but with contents read directly from the config file and Nginx variables).
- Merge contents of various “Nginx locations” (i.e., subrequests) together in a single main request (using echo_location and its friends).
