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 ?
