Apache Tomcat 应用程序的默认会话超时

Question

What is the default session timeout for web applications deployed on Tomcat5.5? Is it browser specific? In my web application, default timeout is mentioned neither in web.xml nor in code.

Answer 1

Open $CATALINA_BASE/conf/web.xml and find this

<!-- ==================== Default Session Configuration ================= -->
<!-- You can set the default session timeout (in minutes) for all newly   -->
<!-- created sessions by modifying the value below.                       -->

<session-config>
  <session-timeout>30</session-timeout>
</session-config>

all webapps implicitly inherit from this default web descriptor. You can override session-config as well as other settings defined there in your web.xml.

This is actually from my Tomcat 7 (Windows) but I think 5.5 conf is not very different
