Hi, Francis.
Thanks for the reply.
I'm gonna try to implement this feature, but I think it will be hard for me.
For now, I'll change the NGINX configuration files to use access_log
according to my needs.
I've one more question about an access_log weird behavior, when it's
configured with a $1 regex return variable.
For instance:
location ~ ^/(system1|system2) {
access_log /var/log/nginx/$1_access.log;
proxy_pass ...;
}
The only way NGINX can write to system1_access.log and
system2_access.log files is when they exist in the specified
directory. Otherwise, the log isn't computed.
I think creating them at the moment of system start is impossible
because the $1 variable isn't initialized yet, but why can't NGINX
automatically create them at the moment they are used?
Thanks again.
Fabiano
