Hello. I have a strange issue where for a POST request having any form data Nginx after version 1.9.4 doesn't log $ssl_protocol (or any other $ssl_*) variable.
I have a configured custom accesslog: log_format main '... $ssl_protocol $ssl_cipher $server_port'; A simple script ( for example from https://nodejs.dev/learn/make-an-http-post-request-using-nodejs ) will generate following accesslog entry with all the variables being empty: [08/May/2021:19:11:50 +0300] ... "axios/0.21.1" - - 443 The moment you remove the form data everything is being logged: [08/May/2021:19:10:58 +0300] ... HTTP/1.1" 200 772 "-" "axios/0.21.1" TLSv1.2 ECDHE-RSA-AES128-GCM-SHA256 443 I tried to debug the requests and see the difference (besides Content-Length) but I wasn't able to pinpoint the issue. I tried various nodejs libraries ('request' etc) and also native approach - all produce same results - empty POST requests are fine, the moment you post any form data the $ssl_* become empty. I can't reproduce it with curl - tried varios requests with and without data, with chunked encoding etc - everything is being logged as expected. One could say that the problem is on the Node side - but what has changed between 1.9.4 and 1.9.5 that breaks the logging? Maybe someone has any suggestions or ideas how to investigate this further?
