[cobalt-users] RAQ 550 - Site preview before DNS propagation

[Pizza Box manager <cobalt-list@xxxxxxxxxxxxx>]

Hello to all,

On our good ol' RAQ4 we used to let users preview their sites before a 
newly added domain name was propagated, our Apache conf was modified like so :

# Added to let users preview their site before DNS setup
AliasMatch ^/preview/([^/]+)(/(.*))? /home/sites/$1/web/$3
# END Added to let users preview their site before DNS setup

So typing http://ourserver/preview/www.usersite.com showed the user site 
contents as soon as it was installed;

This obviously has been changed in the 550, that for example redirect users 
to port 444 to manage their site,
Could anyone confirm what it should be like so that we have the same 
feature on the 550 ?

thanks,
