Reading response headers in log_by_lua filter

marco

Hello,

I'm trying to read the response headers in the log_by_lua filter. I've been unsuccessfully trying to read the "ngx.header" variable in order to do so. What is the best practice for this?

Thanks

Reading ngx.header.HEADER should work in the context of log_by_lua.
The corresponding test case is passing for me:

    https://github.com/chaoslawful/lua-nginx-module/blob/master/t/075-logby.t#L569

If it does not work for you, please provide a minimal and complete
test case that can reproduce the issue on my side :)

Thanks!
