Tomcat8 on CentOS - Session-Tomcat
I have a Tomcat8 (CentOS 7) question. In web.xml under <session-config>
--> <session-timeout> I seen a post on stackoverflow that you can set this
to -1 to keep the session open until the browser is closed. However I
cannot find this in the documentation. Can anyone verify this or point me
in the correct direction for a documented solution. The issue is after 30
minutes the session times out as configured, but anything over 30 does not
work.

See Coty's reply for the -1.
About setting it to more than 30, there are a number of ways that
<session-timeout> could be overridden. You can do it in code, and I
think there are other ways to configure it and I can't remember the
precedence rules.
Can you confirm that the web.xml you are editing is the one actually
being used by Tomcat? Lots of people end up using Eclipse or whatever
that doesn't always do what you expect. Or you forget to copy the
changes into the deployment directory, WAR file, etc.

Re: Tomcat8 on CentOS - Session-Tomcat
Posted by Coty Sutherland <cs...@redhat.com>.
Just following up on our IRC conversation (which happened after this
email) so others can see my response. I was able to find a description
of the session-timeout setting in the XSD here:
http://svn.apache.org/viewvc/tomcat/tc8.0.x/trunk/java/javax/servlet/resources/web-common_3_1.xsd?view=markup#l865
The description there states the following:
"If the timeout is 0 or less, the container ensures the default
behaviour of sessions is never to time out."
So if you set it lower than zero, you're letting the session live
forever (even after the browser closes).
