I want to log what is in the Range header in requests sent to Nginx, in Access Log if possible. How to do that?
You can use something like this
log_format myrange '$remote_addr [$time_local] "$request" $status $body_bytes_sent "$http_referer" "$http_range"';
server {
...
access_log /var/log/nginx/custom_range.log myrange;
}
