Help! Can header() do this?

[sphinxing]

I have a page named "detail.php" only open to members. If not logged in, user will be led to page of "login.php" with 'header(location:"login.php")'.But when some values be submitted to 'detail.php' and not logged in, these values are lost after user's login. Can I forward these values with funtion "header()"? And the keys of those values submitted are unknown and these value/key can't appear in querystring because of secure. I DO NOT mean that session variable and cookie be used.

If you disallow cookies and passing data in the url, what else is left? (PHP is good, but it's going to be quite a while before any mental-telepathy modules are available.) Or is your last line a typo leaving out the "not"--i.e. why couldn't you use sessions?
