How to close connection from openresty

[Alexis Okuwa]

I am building some rate limit code in lua. And want at a point to just close the connection i dont want to send any data. no headers. personal i would like to not even send tcp fin just close it on my end of the kernel i was thinking setting ngx.ctx = nil would help but does not.

This seems to be doing what i am looking for i am not 100% sure from curl i can see it fully closes the connection and does not send headers

[Hamish Forbes]

ngx.status = 444
return ngx.exit(444)

That should do it.

"The non-standard code 444 closes a connection without sending a response header."

BTW, the assignment ngx.status = 444 is not really needed here for
this particular usage IMHO :)
