Check your subdomain regex. Right now, if will only work if your
subdomain is a dot :wink:

It should be (?[^.]*) or (?[^.]+)


Thanks lot, but still wont to work.
And how i set $subdomain to “default” if subdomain doesnt exists?

The “www” part is probably causing a problem too. As the regex is
written it will only match “www...” which I’m
guessing isn’t what you intent. I would instead treat “www” as another
possible subdomain.


Note I haven’t tested this, but it’s similar to a pattern I’ve used. The
$subdomain variable will be either the subdomain, “www”, or will be
empty. It would need some more tweaking to handle multiple subdomains


What is the working form of this? I want to redirect all ..* to .
sub.domain.tld to domain.tld) because I have different domains and
Any help appreciated.
