WildFly 8.1.0 Final Windows Server 2012 R2
I have two sub-domains pointing at this server, and I want requests to each sub-domain to trigger a different war file
default-host is the virtual host that will be used if an incoming request as no Host: header. So to get the requests to your other server, the request sent by the client should have "Host: other-host" in the request header.
A sample HTTP request from client looks like,
GET /Some/Resource HTTP/1.1
Accept: ....
Host: other-host
....
....
See if this works.
