/*
 * Unit test for cookie-based session persistence.
 * See https://glassfish.dev.java.net/issues/show_bug.cgi?id=11648 for
 * details.
 *
 * This test deploys an application which has cookie-based session
 * persistence configured in its sun-web.xml descriptor, with a cookie
 * name equal to ABC.
 *
 * This test accesses a resource that creates a session and checks to make
 * sure that the session is persisted in a response cookie with name ABC.
 * The test then submits this cookie (along with the JSESSIONID cookie
 * that was also received as part of the response) and checks to make sure
 * that the session may be resumed.
