jboss.mod_cluster.proxyList: invalid hosts cause mod-cluster startup to be delayed
----------------------------------------------------------------------------------

                 Key: MODCLUSTER-155
                 URL: https://jira.jboss.org/jira/browse/MODCLUSTER-155
             Project: mod_cluster
          Issue Type: Bug
            Reporter: Bela Ban
            Assignee: Jean-Frederic Clere
         Attachments: tmp.txt

When I set jbss.mod_cluster.proxyList (e.g.) to "http1.dyndns.org:8000,1.2.3.4:8000", mod-cluster does connect to http1.dyndns.org:8000 (assuming it's running), but blocks for 10 minutes trying to connect to 1.2.3.4:8000.

It eventually times out connecting to 1.2.3.4, and then seems to default to 127.0.0.1 !

A better mechanism would be to connect via a timeout (see code below), and to simply skip unreachable httpd instances. The reconnect mechanism can always add httpds (which become reachable) later.

The code to connect to a socket with a timeout would be:
Socket sock=new Socket(new InetSocketAddress("1.2.3.4", 8000), 1000);

This call blocks until it has connected to 1.2.3.4:8000, or until 1 sec has elapsed, whichever occurs first.

In any case, it doesn't block until the OS defined socket connect timeout kicks in; this might be up to 10 mins !
