I am running Plesk 10.3.1 on Media Temple, linux. The www prefix does not work for any of my domains. If I go to http://example.com, I can see my site, but if I go to www.example.com, it goes to the default site for the IP address. Ideally, I would like to use URL rewriting to redirect www.example.com to http://example.com According to this article, www is enabled by default on 10.3.1 http://kb.parallels.com/en/9288 But it is definitely not working. So far, I have tried: Adding www CNAME records to the DNS zone files Adding URL rewriting to htaccess or vhost.conf files All of the support I have seen on this issue seems to refer to earlier versions of Plesk that included domain administration. Any help would be appreciated.
