Hi, If I create a variable, default to blank:
map upstream_env $upstream_env { default ""; } and log it in access log (log_format has $upstream_env). I see a "-" in the log file, which is as expected, but for a 2-way SSL virtual host, I don't see the "-", just blank. Is that a bug? For now, if I change above map to : map upstream_env $upstream_env { default "-"; } I can then see the - in the access log for 2-way SSL virtual host. Thanks! Frank
