Subject Re: disabling session management
Date Mon, 11 Oct 2010 12:54:46 GMT
Hi Christopher

> Which classes, specifically?

Thousands of Session instances inside the sessioins attribute of the
org.apache.catalina.session.StandardManager.
In theory we are not calling getSessions on the middle tier and as you
mentioned, we have no JSPs either.

However, we might be passing a jsession parameter from the frontend to
the middle tier. Would that be an issue, causing the session to be
created in the middle tier?

In the only place I see any reference to it is here:
http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/catalina/session/StandardSessionFacade.html#setMaxInactiveInterval(int)

And it says that "A negative time indicates the session should never
timeout.". there is no mention about setting as "0".

Emerson
