Hi,i have a question about configuration of mod_cluster .

I set proxy-list element in domain.xml, which defines the list of httpd servers with which the AS will initially communicate.

There is only one httpd server,if i have two httpd servers communicated,how to config?

I tried to use the command-line management interface to set more proxies for each server,it seems working.:

[domain@10.19.222.52:9990 /] /host=master/server=server-one/subsystem=modcluster:add-proxy(host=10.19.222.50,port=6666) 
{
    "outcome" => "success",
    "result" => undefined
}
[domain@10.19.222.52:9990 /] /host=master/server=server-one/subsystem=modcluster:add-proxy(host=10.19.222.51,port=6666) 
{
    "outcome" => "success",
    "result" => undefined
}
[domain@10.19.222.52:9990 /] /host=master/server=server-one/subsystem=modcluster:list-proxies
{
    "outcome" => "success",
    "result" => [
        "pre05web02.cnxmxt.com:6666",
        "pre05web01.cnxmxt.com:6666"
    ]
}
[domain@10.19.222.52:9990 /] /host=slave/server=server-one/subsystem=modcluster:add-proxy(host=10.19.222.50,port=6666) 
{
    "outcome" => "success",
    "result" => undefined
}
[domain@10.19.222.52:9990 /] /host=slave/server=server-one/subsystem=modcluster:add-proxy(host=10.19.222.51,port=6666) 
{
    "outcome" => "success",
    "result" => undefined
}
[domain@10.19.222.52:9990 /] /host=slave/server=server-one/subsystem=modcluster:list-proxies
{
    "outcome" => "success",
    "result" => [
        "pre05web02.cnxmxt.com:6666",
        "pre05web01.cnxmxt.com:6666"
    ]
}

But it was not synchronized to XML file,once restarted appliaction server,it would rollback.

[domain@10.19.222.52:9990 /] /host=master/server=server-one/subsystem=modcluster:list-proxies
{
    "outcome" => "success",
    "result" => undefined
}
[domain@10.19.222.52:9990 /] /host=slave/server=server-one/subsystem=modcluster:list-proxies
{
    "outcome" => "success",
    "result" => undefined
}
[domain@10.19.222.52:9990 /] 

Versions of my softwares as follows:

wildfly-8.0.0.Beta1

mod_cluster-1.2.0.Final-linux2-x64-ssl.tar.gz

I also tried JBOSS AS7 with CLI,but commands are not available.It has no add-proxy command:

[domain@10.19.222.52:9999 /] /host=master/server=server-1/subsystem=modcluster:add-proxy(host=10.19.222.51,port=6666) 
Failed to get the list of the operation properties: "JBAS014753: There is no operation add-proxy registered at address [("subsystem" => "modcluster")]"
[domain@10.19.222.52:9999 /] /host=master/server=server-1/subsystem=modcluster:read-operation-names
{
    "outcome" => "success",
    "result" => [
        "list-proxies",
        "read-attribute",
        "read-children-names",
        "read-children-resources",
        "read-children-types",
        "read-operation-description",

        "read-proxies-configuration",
        "read-proxies-info",
        "read-resource",
        "read-resource-description",
        "refresh",
        "reset"
    ]
}
[domain@10.19.222.52:9999 /] 

A set of commands with WildFly8 as follows:

[domain@10.19.222.52:9990 /]  /host=master/server=server-one/subsystem=modcluster:read-operation-names
{
    "outcome" => "success",
    "result" => [
        "add-proxy",
        "disable",
        "disable-context",
        "enable",
        "enable-context",
        "list-proxies",
        "read-attribute",
        "read-children-names",
        "read-children-resources",
        "read-children-types",
        "read-operation-description",
        "read-operation-names",
        "read-proxies-configuration",
        "read-proxies-info",
        "read-resource",
        "read-resource-description",
        "refresh",
        "remove-proxy",
        "reset",
        "stop",
        "stop-context",
        "undefine-attribute",
        "write-attribute"
    ]
}

OK.I know how to config one more httpd servers，just use proxy-list element:

<mod-cluster-config advertise-socket="modcluster" proxy-list="10.19.222.50:6666,10.19.222.51:6666">

But why using CLI can't  write to the XML files and it rollback when restart.

:add-proxy() is an operation that affects only runtime.

To change the configuration permanently, you need to use :write-attribute() operation:

[standalone@localhost:9990 /] /subsystem=modcluster/mod-cluster-config=configuration/:write-attribute(name=proxy-list,value="localhost:6666")
{
    "outcome" => "success",
    "response-headers" => {
        "operation-requires-reload" => true,
        "process-state" => "reload-required"
    }
}

I suppose it's a little confusing. Any suggestion for improvement?
