title: Changing system properties in Apache Tomcat 7
body: <p>I have found lots of links saying that if I want to change the name of my session cookie all I have to do is modify the following system properties.</p>
  
  <pre><code>org.apache.catalina.SESSION_COOKIE_NAME
  org.apache.catalina.SESSION_PARAMETER_NAME
  </code></pre>
  
  <p>How do I do this? I looked inside Catalina.properties but I'm not sure. Is there a way of modifying these properties through Context.xml,server.xml, or web.xml?</p>
