what I found out in the meantime is that you CAN use cookies and headers, just like you said, but my particular problem arose because a notice was issued for an undefined variable; I didn't check correctly for it's existence. so any output, and also output like notices, warnings and errors, just anything you might get in a development situation, outputs headers and the consecutive calls to header() or setcookie() will fail.
for clarity, this was the output: notice; undefined index: bla in file.php on line 162 #wrong check in if condition warning: cannot add header infromation - headers already sent by (output started at file.php) in file.php on line 164#wetcookie call, but notice has already been sent out, so this will fail -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
