Seems like a short rule for Plack::Middleware::Conditional; look at $env->{HTTP_HOST} and dispatch by that.

If you don't want to change any application code, you could have separate instances of Starman listening at different ports, and then have a user-facing Apache instance that runs a reverse proxy for each subdomain.

I use a similar setup for a host that started off with only Apache, and now forwards some domains to a Mojolicious application, and it works fine.

Or you could have a user-facing ngix/lighthttpd/perlbal instance that runs a reverse proxy for each subdomain :) Plack::Middleware::ReverseProxy

example reverse proxy config for apache/apache2/ngix/lighthttpd http://www.omakase.org/perl/starmanreverseproxyab.html

I think its just a matter of using

--listen localhost --listen localpost --listen localfoobar

$urlmap->map( "http://localhost/" => $app1);
$urlmap->map( "http://localpost/" => $app2);
$urlmap->map( "http://localfoobar/" => $app3);

I'm not sure you need the multiple --listen options if all the hostnames bind to the same IP

If anyone still needs this, I've created a CPAN module to help with this:

Plack::App::HostMap
