This is a very simple HTML page that merely is set up to redirect back to the original script that generated the cookies. At this point if I try and print out what is in $ENV{"HTTP_COOKIE"} I get absolutely nothing. I was hoping to get the cookies that were originally set up in the initial call of the script.

I'd question a couple things:

 1) Are they actually set? Check your browser's cookie store to see
if they're there or establish a telnet HTTP session and see if it's in
the response. Setting cookies and doing a HTTP redirect in the same
header doesn't work on some servers (notably older IISes).

 2) If they are set, do they have the correct url and path?

 3) Is your environment cleansing them? This is unlikely but
depending on your webserver, make sure there aren't any handlers
eating the cookies before they get to you.
