Introduction

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


Steps

Init Parameters

Context Parameter Name Default Value Description
org.eclipse.jetty.servlet.SessionCookie JSESSIONID Session cookie name defaults to JSESSIONID, but can be set for a particular webapp with this context param.
org.eclipse.jetty.servlet.SessionIdPathParameterName 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.eclipse.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.eclipse.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.eclipse.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.
org.eclipse.jetty.servlet.CheckingRemoteSessionIdEncoding false

Example

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.eclipse.jetty.servlet.SessionCookie</param-name>
    <param-value>XSESSIONID</param-value>
  </context-param>
  <context-param>
    <param-name>org.eclipse.jetty.servlet.SessionIdPathParameterName</param-name>
    <param-value>xsessionid</param-value>
  </context-param>
  ...
</web-app>

or, they can be configured on a web application, either in code, or in a Jetty context xml file equivalent:

<Configure class="org.eclipse.jetty.webapp.WebAppContext">
  <Set name="contextPath">/test</Set>
  <Set name="war"><SystemProperty name="jetty.home" default="."/>/webapps/test</Set>
 
  ...
 
  <Call name="setInitParameter">
        <Arg>org.eclipse.jetty.servlet.SessionCookie</Arg>
        <Arg>XSESSIONID</Arg>
  </Call>
  <Call name="setInitParameter">
        <Arg>org.eclipse.jetty.servlet.SessionIdPathParameterName</Arg>
        <Arg>xsessionid</Arg>
  </Call>
</Configure>

or they can be configured directly on a SessionManager instance, either in code or the equivalent in xml:

<Configure class="org.eclipse.jetty.webapp.WebAppContext">
  <Set name="contextPath">/test</Set>
  <Set name="war"><SystemProperty name="jetty.home" default="."/>/webapps/test</Set>
 
   ...
 
  <Get name="sessionHandler">
     <Set name="sessionManager">
         <New class="org.eclipse.jetty.server.session.HashSessionManager">
            <Set name="sessionCookie">XSESSIONID</Set>
            <Set name="sessionIdPathParameterName">xsessionid</Set>
         </New>
     </Set>
  </Get>
</Configure>
