--------------------------------------------------
Key: MODCLUSTER-273
URL:
https://issues.jboss.org/browse/MODCLUSTER-273
Project: mod_cluster
Issue Type: Bug
Affects Versions: 1.1.4.Final
Reporter: Christoph Gostner
Assignee: Jean-Frederic Clere
Labels: clustering, httpd, jboss-as7
Fix For: 1.2.0.Beta5
The change of the {{sticky-session-force}} attribute requires a httpd restart.
Environment:
Apache with {{mod_cluster}} and two JBoss AS7 (standalone mode but with ha
configuration).
Initial setting:
# {{sticky-session=true}}
# {{sticky-session-force=false}}
Example output:

Switch to node c178529b

29 c178529b

The documentation for {{sticky-session-force}} says:
{quote}
Indicates whether the httpd proxy should return an error in the event that the balancer
is unable to route a request to the node to which it is stuck. This property is ignored if
stickySession is false.

We change {{sticky-session-force}} to {{true}}. Now I expect an 503 error ...
But nothing happens...

... after a restart of httpd and JBoss the expected error happens:

Failed to open "http://ci.objectbay.com:8000/demo7/". Error code - 503.
Broken between 3 and 0 for 0 seconds.

It seems that the change in the settings requires a complete restart of the cluster
environment.
