Trying to setup a redirect from a .com to a .org, I've recently screwed up a personal multisite, where all the subdomains (parked domains) still work quite fine, but the primary site (the one with the more important content) is broken. So I'm rebuilding everything. You can see the mess on http://carlorizzante.com and http://lesstools.org and http://lesstools.com (other subdomains are empty and not interesting for the topic).
Sadly I ended up at this point when I tried to setup the redirect.
To better explain, lesstools.com should have redirect to lesstools.org, where the latter is part of the network, and the .com is just a parked domain, with a redirection assigned through the cpanel (Hostgator).
Now, I've two questions. First, is the WordPress MU Domain Mapping plugin still necessary to map domains in a network? Or, as I've read in this forum since WordPress 3.1, is it no more necessary, having WordPress 3.1 built in all the necessary mapping thing?
Second question, what is the best practice for setting up a redirection? If I want subdomain.com to redirect to subdomain.org, should I manage the two domains internally the network, mapping both of them with one specific subsite and choosing which one of the two has to be the primary domain for that subsite, or should I redirect one of the two via cpanel?
Thanks in advance,
