Hi Ajay, If you generate the configuration, and issue a nginx reload – it won't cause any downtime. The master process will reread the configuration, start new workers, and gracefully shut down the old ones. There's absolutely no downtime involved in this process.

We are wanting to implement a solution, wherein the user gets proxied to the appropriate local-url, depending upon the credentials. Following architecture works like a charm (thanks a ton tofran...@daoine.org<mailto:fran...@daoine.org>, without whom I would not have been able to reach here) :: #################################################### server { listen 2000 ssl; ssl_certificate /etc/nginx/ssl/nginx.crt; ssl_certificate_key /etc/nginx/ssl/nginx.key; location / { auth_basic 'Restricted'; auth_basic_user_file /etc/nginx/ssl/.htpasswd; if ($remote_user = "user1") { proxy_pass https://127.0.0.1:2001<https://127.0.0.1:2000>; } if ($remote_user = "user2") { proxy_pass https://127.0.0.1:2002<https://127.0.0.1:2000>; } # and so on .... } } #################################################### Things are good, except that adding any new user information requires reloading/restarting the nginx server, causing (however small) downtime. Can this be avoided? Can the above be implemented using some sort of database, so that the nginx itself does not have to be down, and the "remote_user <=> proxy_pass" mapping can be retrieved from a database instead? Will be grateful for pointers. Thanks and Regards, Ajay
