I am currently running Tomcat 6.0.24 on a Windows Vista machine.
The web app I am developing will be deployed to a cloud, where server affinity
will be thrown to the wind. Thus, instead of relying on tomcat to manage my
session, I am instead managing the session via manual cookies and a database.
Being that I cannot leverage the tomcat session, I don't want to create a
session at all. This has a two-fold benefit:
1) Slight performance increase due to avoiding session creation overhead
2) I can put a session listener in place to log an error if ever a session
is created, to ensure that we are not using the tomcat session in the
development environment where everything would appear to be fine until we
deploy to the cloud.
According to JSP spec, I believe I should be able to use the following
directive to prevent a session from being created by my JSPs: <%@ page
session="false" %>. However, even when doing so, I am still getting a session
created by the internals of the JSP container. Is there something I am doing
wrong? Is it possibly a bug in Tomcat 6.0.24 (couldn't find it on Bugzilla)?
Or is it simply a "necessary evil"?
The generated JSP code that is triggering the session is: pageContext =
_jspxFactory.getPageContext(this, request, response, null, true, 8192, true);
Below is the relevant portion of an exact stack trace:
