title: Value of JSESSIONID is not changed on invalidating session
body: <p>I needed to change JSESSIONID's domain to ".something.com" in a context.xml file:</p>
  
  <pre><code>&lt;Context path="/test" sessionCookiePath="/" sessionCookieDomain=".something.com" useHttpOnly="true" /&gt;
  </code></pre>
  
  <p>After that, when I perform a httpSession.invalidate() the session is reset but JSESSIONID value does not change. </p>
  
  <p>I'm using Java 7, Spring MVC and Tomcat 7. I also tried to remove the JSESSIONID cookie manually, but it seems that Tomcat or Spring are not letting I change its value.</p>
  
  <p>This may difficult troubleshooting on my system. I'd like to know if it's possible to change this behavior either on Spring or in Tomcat.</p>
