Using shopnc for secondary development, non-80 port, login 302 jump session lost, has anyone encountered this?

Due to project reasons, I opened a port 8080 to run shopnc, but the session is still there at the login_check step. After logging in, the session is gone when I perform a 302 jump to a new page for output. Has anyone encountered similar problems? In the apache environment, session.use_trans_sid in php.ini is already = 1.

It may be a cross-domain problem,
