Apache/htaccess - password protect a site by domain name

Question

Is it posible to protect a website if the site was called by a given domain name?

e.g.

www.domain.com -> no password protection
www.domain.net -> password protection

Both of the URLs are routed to the same document root.

Answer 1

If you have multiple virtualhosts, you can add password protection to one and not the other via the following directive:

<VirtualHost *:80>
DocumentRoot /www/example1
ServerName www.example1.com
</VirtualHost>

<VirtualHost *:80>
DocumentRoot /www/example1
ServerName www.example1.org
<Directory "/www/example1">
AuthType Basic
AuthName "Protected Site"
AuthUserFile /etc/httpd/passwd
Require user joeuser
</Directory>
</VirtualHost>
