[JBoss JIRA] (MODCLUSTER-318) make connector address user configurable

by James Livingston (JIRA)

[ https://issues.jboss.org/browse/MODCLUSTER-318?page=com.atlassian.jira.pl... ] James Livingston commented on MODCLUSTER-318: --------------------------------------------- This would also be useful to handle the case when there is a NAT between httpd and the backend, in which case the connector binding address is not the address that httpd can reach it on. That has been brought up a few times in the forum such as https://developer.jboss.org/thread/249888 > make connector address user configurable > ---------------------------------------- > > Key: MODCLUSTER-318 > URL: https://issues.jboss.org/browse/MODCLUSTER-318 > Project: mod_cluster > Issue Type: Feature Request > Affects Versions: 1.2.1.Final > Reporter: Aleksandar Kostadinov > Assignee: Paul Ferraro > > MODCLUSTER-168 introduced a change that broke some existing working configurations relying on using IP instead of a hostname. Also it is likely to be the cause of MODCLUSTER-91. > To have everybody happy, this needs to be made configurable, perhaps a system property that user can set to force a particular IP or hostname. It would also be very useful if there is a special value that makes the behavior same as before the changes in MODCLUSTER-168. For example setting the value to -1 would return the original behavior. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
