Hello Maxim,

I am surely aware of how server requests are matched in nginx. Thanks for the info though.

The thing is, I have multiple virtual hosts configured all with server_name defined, of course. Then there's default fallback server configured as this:

# default fallback server
server {
listen 80 default_server;
server_name _;
return 444;
}

After reading your reply I went to check my error logs and the strange thing is that error messages go both into one of my virtual host server's error log with correct data (remote address, server name, etc.), but also go to nginx default (?) error_log with entries that I reported? How come, if the virtual host server being accessed using the slowhttptest program is clearly "testsite" with its own error_log, yet the connection limit error message is reported in two error logs?

slowhttptest -c 1000 -r 1000 -X -u http://testsite

results:

/var/log/nginx/testsite/error_log:

Could it have anything to do with the fact that limit_zone and limit_conn are defined on http level? Yet, I think the behaviour is not fully correct.

I would appreciate your feedback,
