We're also capturing "wildcard" subdomains in the vhost with:

if ( $host ~* "^([a-zA-Z]+[a-zA-Z0-9]*)\.mysite\.tld$" ){
    set $files custom;
}

so if someone hits "a8df15f.mysite.tld" they get a custom homepage, but 
"18sdf351f.mysite.tld" is invalid and therefore they get the "home 
page". Can this also be reproduced with the "map" directive?
