How to whitelist a user agent for nginx?
If only need to whitelist by user agent (not IP or other conditions) and don't want to recompile Nginx just to include the auth_request module you can also use the map directive to check the user agent and conditionally disable basic auth.
map $http_user_agent $auth_type {
default "Restricted";
~^Mozilla "off";
}
server {
location / {
auth_basic $auth_type;
}
}
This will turn off basic auth for Mozilla user agents.
