Hi,
you could also use a SessionListener an invalidate sessions immediately
after being created or you could write your own implementation of
|org.apache.catalina.Manager
|http://tomcat.apache.org/tomcat-6.0-doc/config/manager.html and
configure it to be used instead of the default manager.

What could be the reason for SYN requests of the Apache that never get

In case you have a lot of HTTPS traffic, you'll find that having Apache
handle SSL is faster than the Java implementation that Tomcat can offer.
IMHO for HTTP traf
Remove the servlet-api.jar from your web apps. This jar is provided by
Tomcat already. You might need it to build your app, but don't deploy it.

No... catalina.bat or .sh (at least TC 5.x+) can guess CATALINA_HOME by

Hi,
somehow I don't get it. Why not simply assume that JAVA_HOME is properly
set on every environment you want to run Tomcat? You need a proper Java
installation anyway. Then there should not be any need to "configure"
