> EnableOptions and SSL configuration
> -----------------------------------
>
> Key: MODCLUSTER-401
> URL: https://issues.redhat.com/browse/MODCLUSTER-401
> Project: mod_cluster
> Issue Type: Bug
> Components: Native (httpd modules)
> Affects Versions: 1.2.8.Final
> Environment: HP-UX Apache HTTP Server 2.2.15, RHEL Apache HTTP Server 2.2.22, perhaps platform independent...
> Reporter: Michal Karm
> Assignee: Jean-Frederic Clere
> Priority: Major
> Fix For: 1.2.14.Final
>
>
> As a follow up on MODCLUSTER-400 and a documentation effort for *EnableOptions* logic, I tried to add {{EnableOptions}} to the configuration so as to allow for a "cping/cpong" emulation of the famous AJP feature.
> With the following {{mod_cluster.conf / httpd.conf}} (standalone-ha.xml being the same as in MODCLUSTER-400's description):

> Why is the JBoss EAP residing on {{10.16.92.191:8645}} trying to request SSL Proxy on the virtual host {{10.16.92.191:2081}}? The result is {{Status: NOTOK}} on mod_cluser manager console.
> I tried to remove that {{10.16.92.191:2081}}, so as the {{10.16.92.191:8745}} is the only one ([^hp-ux_error_log-EnableOptions-single-vhost.zip]):

> Why isn't the {{10.16.92.191:8745}} enough? Is it a configuration error or a ProxyPass/SSL integration bug?
