Of course there is - don't create a session in the first place.  Sessions a=
re only created automatically by Tomcat when a login occurs (and I presume =
the Google bots aren't supplied with authentication credentials); otherwise=
 it's *your* webapp that has specified that a session be created.

> Question is: Is there a way to configure tomcat to only use cookies

Again, it's *your* webapp that's appending the session id by calling encode=
URL(); if you only want to use cookies, don't do that.

> Also the name ' JSESSIONID' is configurable?

It's required by the servlet spec, but at least in the current Tomcat level=
 (6.0.24) you can change it by setting the org.apache.catalina.SESSION_PARA=
METER_NAME system property:
http://tomcat.apache.org/tomcat-6.0-doc/config/systemprops.html#Sessions
