Many thanks to [csnyder] and [Tim Lieberman] for their helpful suggestions about header ().
I now have that part of things working fine. However, because there is an implicit exit; after issuing the call to header (), I'm uncertain if the $_SESSION variables are being set properly. When I trace them at the end of one page they are all there ($_SESSION['userid'] = $userid; $_SESSION['badgename']=$badgename;), but when I examine the $_SESSION array at the start of the next page, the variables do not exist. My guess is that by short-circuiting any nrmal end-of-script processing, I may be bypassing the write of the $_SESSION array to the temporary file. This feels like forcing a buffer-flush when working with low-level disc IO. Is there any known reason for $_SESSION variables to disappear in such circumstances? Does anyone have any other ideas? Thanks for any pointers, Tony
