Redmine

Hi, I have just installed redmine on my server and it works perfectly under http://localhost/redmine/public.

The docs stats that to access redmine I must set my apache's documentroot to /var/www/redmine/public so that I access redmine on http://localhost, but if I do that, I can not access other applications on that server, for example, http://localhost/owncloud.

Is there any way of configuring apache so that I can access redmine trhough http://localhost/redmine and other applications as well like http://localhost/owncloud?

Thanks
