Hello,

As far as I know, it's impossible using Nginx.
But you can archive the same result using only 'access_log' statement
into 'permanent' location.
Just mount your external drive 'nginx' directory over /var/log/nginx like:
mount -o bind /externalhdd/log/nginx/ /var/log/nginx/

If it is unsuitable for you to 'hide' whole directory, you can create
a subdirectory for your logs and bind external hdd dir there:
mount -o bind /externalhdd/log/nginx/ /var/log/nginx/mysitelogs/

Hope this helps.
