I'm using the following code to block users on my staging subdomain.
AuthName "PRIVAT"
AuthType Basic
AuthUserFile /var/www/mydomain.com/.htpasswd
require valid-user
Since I'd like to use the same .htaccess for staging and production I'd like to add an condition if HTTP_HOST = staging.mydomain.com so that only the staging environment is password prodected? Is this possible?
