 *  ("jvmRoute not reset in JSESSIONID Cookie during fail-over")
 *
 * This unit test defines a system property with name jvmRoute and value
 * MYINSTANCE, invokes a servlet that creates a session, and expects a
 * JSESSIONID response cookie.with the string ".MYINSTANCE" appended to its
 * session id.
 *
 * In a subsequent request, it includes the JSESSIONID from the response
 * and invokes a servlet that resumes this session. This servlet first checks
 * to make sure that the string ".MYINSTANCE" has been removed (by the
 * container) from the session id. The servlet then adds its own cookie to
 * the response, in order to mimic the root cause of IT 7101. The client
 * verifies that the response still contains a JSESSIONID response cookie
 * with the string ".MYINSTANCE" appended to its session id.
