Backport MODCLUSTER-168 to 1.0.10.GA - mod_cluster should use hostname provided in address instead a IP address

The CONFIG message from JBoss to apache is always formatted like the following and still uses the resolved ip address instead of the bound to host name:

Port=8009, Host=127.0.0.1, Type=ajp, StickySessionForce=No, Maxattempts=1

Even if the Connector is defined like:

<Connector port="8009" address= "localhost" protocol="AJP/1.3" redirectPort="8443" />

This can cause issues if apache needs to proxy to JBoss through the host name and not the ip. This could be corrected by using InetAdress.toString() in org.jboss.modcluster.Utils and parsing the hostname out of this result if provided, for example:

public static String getAddress(Connector connector)
{
Object address = IntrospectionUtils.getProperty(connector.getProtocolHandler(), "address");

if (address == null) return "127.0.0.1";

if (address instanceof InetAddress)

{ String addressString = ((InetAddress) address).toString(); int index = addressString.indexOf("/"); return (index > 0) ? addressString.substring(0, index) : addressString.substring(1); }

else

{ return (String) address; }

}
