When I create a new website and add a domain, the virtual host is set up for both www and non-www requests. If would like to redirect all www requests to the non-www domain, I have to go into the overrides panel for the site and manually add something like:
if ($host ~* ^www\.(.*)) {
set $host_without_www $1;
return 301 $scheme://$host_without_www$request_uri;
}
to the VirtualHost config. Many control panels include an option to automatically redirect www or non-www traffic to the alternate domain, this seems like it would be useful.
