In a virtual host, I setup two different <Location> blocks for which the access is restricted by two basic authentication htpasswd files. One htpasswd contains different usernames + a common user name. The other htpasswd file only contains the common user name.

My problem is that once users connect a location with the common user name, they have immediate access to the other location without being asker for a different user name.

Is there a way to restrict the username access only to the corresponding htpasswd file? Is there a way for users to ask to be re-prompted for another username/password?
