[otrs] Go directly to customer login?

I would like to be able to send my customers directly to the customer login page via helpdesk.domain.com without having to type /otrs/customer.pl at the end. How do I setup my vhost file to do that? I have it pointing to /opt/otrs/var/httpd/htdocs right now but that goes to the agent login. Ultimately, I want to have helpdesk.domain.com go to the customer login and hdagent.domain.com go to the agent login. Any thoughts? Thank you, Joe Fusco
