Q: about "best" way for remove www in hostname in nginxish

[Aleksandar Lazic]

Dear readers,

after reading

http://nginx.org/en/docs/http/server_names.html#regex_names

and googleing

https://www.google.at/search?q=nginx+remove+www+subdomain

I have a 'best solution' question.

I have the following customer request.

The 'normal User' type almost every time a www.subdomain.domain.at into 
they browser,
which does not exist but the subdomain.domain.at exists.

I would now add the follwing into my nginx.conf.

###
server {
server_name   ~^(www\.)?(?<domain>.+)$;

return http://$domain/;
}
###

Is this the cleanest way in nginxish?

Thanks for help
Aleks
