I thought the communication between appservers and httpd mod-cluster uses AJP by default ? Has this changed to HTTP ? I changed the following 2 things (in standalone-ha.xml in AS 7): <connector name="ajp" protocol="AJP/1.3" socket-binding="ajp" max-connections="400"/> <socket-binding name="ajp" port="8009"/> and then "netstat -na |grep 8009" and the mod-cluster-manager "show-info command" actually showed that AJP was now used, compared to HTTP before. Do I have to enable this to actually make the workers communicate with httpd via AJP and not via HTTP ? Or am I mistaken and this is only used for MCMP, but not request/response forwarding ? -- Bela Ban Lead JGroups (http://www.jgroups.org) JBoss / Red Hat
