What version of Jboss AS?
There ware some experimental patches to jbossweb that add support for this, but here is no elegant solution atm.
There are few tricks how you can make it behave as you want but noting really elegant, see https://bugzilla.redhat.com/show_bug.cgi?id=995411 for example.
However, in WildFly 8 with undertow subsystem we added support for scenarios like this from design up.
take a look for example how to configure it https://community.jboss.org/message/857103
This is EAP 6.2.0 / AS 7.3.0
I'll take a look at that property org.apache.catalina.connector.USE_IP_PORT_FOR_ALIAS, though the other thing is how these aliases will be pushed to the mod_cluster at httpd and if mod_cluster will handle them properly.
So I setup system property org.apache.catalina.connector.USE_IP_PORT_FOR_ALIAS=true and virtual-server aliases like <alias name="*:80"/> etc.
Direct access and access via mod_cluster with UseAlias 0 works, but there's no virtual host separation with UseAlias 0.
With UseAlias 1 there's no match and request fails. I also tried with exact host names instead of wildcards (because it seems wildcards can't be used unfortunately: Can I use aliases with wildcards in mod_cluster and JBoss?) but there was no difference, it just doesn't work when ports are specified.
So it seems mod_cluster can't handle such configurations. Is there anything to do about it? It's mod_cluster 1.2.6.
Note that mod_cluster manager lists those aliases properly - *:80
EDIT: moved to mod_cluster space which is probably more appropriate at this point
