/*
 * Unit test for https://glassfish.dev.java.net/issues/show_bug.cgi?id=3374
 * (FORM authenticator should issue a redirect (instead of a request
 * dispatch "forward") to the login page).
 *
 * This unit test has been reworked in light of the fix for CR 6633257:
 * Rather than issuing a redirect over https to the login.jsp login page
 * (which is protected by a transport-guarantee of CONFIDENTIAL), the
 * redirect over https will be applied to the original request (that is,
 * to protected.jsp), followed by a FORWARD dispatch to login.jsp.
 *
 * This unit test verifies only that the target of the https redirect is as
 * expected, and does not perform the actual FORM-based login.
