Not sure if this is a Tomcat or an IDEA bug so I'm throwing this out there to see if anyone else has seen this.
My webapp sets cookies="false" in the context descriptor to workaround Safari's picky behavior picking up the session cookie. Works great in my standalone tomcat but seems to be ignored when running with the integration plugin.
It seems any url that starts with http://localhost will not get the session id in the URL but if I use 127.0.0.1 it will.
Any idea why this might be?
