[mod_cluster-issues] [JBoss JIRA] (MODCLUSTER-645) Different handling of max-attempts parameter on Undertow and httpd implementation

     [ https://issues.jboss.org/browse/MODCLUSTER-645?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jan Kašík updated MODCLUSTER-645:
---------------------------------
    Description: 
The behavior of balancer is different on httpd in comparsion with Undertow implementation when max-attempts parameter is set.

* *Undertow*: max-attempts is total count of requests made by balancer in failover scenario. When max-attemps is set to 1 and target worker fails after first attempt made by balancer, no further attempts are made.
* *httpd*: max-attempts is count of retries made by balancer after first attempt fails. When max-attempts is set to 1 and target worker fails after first attempt made by balancer, second worker is chosen and request is sent towards it.

This doesn't seem right and I suggest to unify behavior across implementations.
