title: Grails and Subdomains
body: <p>Does Grails know anything about sub-domains (i.e. subdomain.domain.com) ?   I don't see it discussed in the <a href="http://grails.org/doc/2.0.x/guide/single.html" rel="noreferrer">manual</a>.   Is this purely an app server/web server issue?   Can be tied into grails controllers, either statically or dynamically?</p>
