How do you do for a Domain Alias, work as a permanent redirect apache tag? For example, I have two domain: domainx.com domainx.net In this case an alias works this way, if someone writes domainx.net, is redirected to domainx.com which is correct, but the url is domainx.net and what I need is that the url show the domainx.com. In other words the behavior I need is the equivalent of a permanent redirect.
