Thanks, all.

My option number 3 does not work: 

system "echo rm $session_file | at now + 1 minute";

[download]
The session file is created, the job shows up in atq, but it fails silently. It's the 'silently' part that is most maddening. Hm maybe I should direct errors somewhere..but the apache user isn't in /etc/at.deny, and indeed I forced a shell on the user and it worked okay--I thought cdarke might be on to something :-)

gmargo: I hear you loud and clear. I think I'm going to check out moritz suggestion and check out CGI::Session. However, in this case I'm putting in the 'at' right after creating the session file, so at least it isn't from user input. So I *presume* it's okay, but yeah, I'll check out CGI::Session :-). I hear ya loud and clear, and appreciate the input.

Really now it just bugs me that I don't know why it fails.
