Aegir redirect url to actual site I’d like to redirect the: aegir-server.com/a-site-url.com to a-site-url.com without hacking Aegir and based on a pattern so any future site will follow this type of redirect. Is it possible through Aegir?

(Aegir redirects the : aegir-server.com/node/site_id/goto_site to the site, but this is not what I need)
The easiest way would be to edit the .htaccess file of your hostmaster platform and add something like

RewriteRule ^(.*\.com) http://$1 [L,R=301]

Note that you have to reload apache as Aegir integrates the htaccess file into the vhost config.
