hide ip address from JSESSIONID

822 views Asked by At

When I inspect my web application from the browser I get this cookie: JSESSIONID="5Wz6Tjwp74IDYATgzt1W-VP1FmOHMTjmrk4WnbcL.ip-172-39-20-122".

I want to remove the IP address from the JSESSIONID. I'm using Wildfly 9.0.2.

The session id suffix (anything after the dot) is the instance-id attribute in undertow subsystem. https://wildscribe.github.io/Wildfly/9.0.0.Final/subsystem/undertow/index.html

It defaults to ${jboss.node.name} which you could set on command line using -Djoss.node.name

It's nillable, so you could actually remove it and nothing will be suffixed.
