Configuring Session Information

The following configuration can be applied to modify the session characteristics of a web application:

Context Parameter Name	Default Value	Description
org.mortbay.jetty.servlet.SessionCookie	JSESSIONID	Session cookie name.efaults to JSESSIONID, but can be set for a particular webapp with this context param.
org.mortbay.jetty.servlet.SessionURL	jsessionid	Session URL parameter name. Defaults to jsessionid, but can be set for a particular webapp with this context param. Set to "none" to disable URL rewriting.
org.mortbay.jetty.servlet.SessionDomain	-	Session Domain. If this property is set as a ServletContext param, then it is used as the domain for session cookies.If it is not set, then no domain is specified for the session cookie.
org.mortbay.jetty.servlet.SessionPath	-	Session Path. If this property is set as a ServletContext param, then it is used as the path for the session cookie. If it is not set, then the context path is used as the path for the cookie.
org.mortbay.jetty.servlet.MaxAge	-1	Session Max Age. If this property is set as a ServletContext param, then it is used as the max age for the session cookie. If it is not set, then a max age of -1 is used.

The above can either be set as <context-param>s in a web application's WEB-INF/web.xml file like so:

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app
   xmlns="http://java.sun.com/xml/ns/javaee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
   version="2.5">
...
<context-param>
    <param-name>org.mortbay.jetty.servlet.SessionCookie</param-name>
    <param-value>XSESSIONID</param-value>
  </context-param>
<context-param>
    <param-name>org.mortbay.jetty.servlet.SessionURL</param-name>
    <param-value>xsessionid</param-value>
</context-param>
...
</web-app>

or, they can be set in a Jetty context xml file that configures a web application:

<Configure class="org.mortbay.jetty.webapp.WebAppContext">
  <Set name="contextPath">/test</Set>
  <Set name="war"><SystemProperty name="jetty.home" default="."/>/webapps/test</Set>

   ...

  <Set name="initParams">
    <Map>
      <Entry>
       <Item>org.mortbay.jetty.servlet.SessionCookie</Item>
       <Item>XSESSIONID</Item>
      </Entry>
      <Entry>
       <Item>org.mortbay.jetty.servlet.SessionURL</Item>
       <Item>xsessionid</Item>
      </Entry>
    </Map>
  </Set>
</Configure>
