Hi all,

In Rails3 we can define a constraint for subdomain as such:  
constraints(:subdomain =\> “support”) do  
…  
end

But if we are using development web server like webrick, how would we  
be able to test it? Anybody has got any hint or insights on this?

Your help is kindly appreciated.

Kind regards,  
Joshua
