I saw that and wondered (the code was written by someone else). It still
doesn't explain why it worked for a few months and then just up and quit.
The error might not have been picked up if MacPerl returns the HTTP headers
instead of undefined or nothing. The failure was actually in a regex that
followed the assignment to HTTP_REFERRER. It could be that the regex worked
on the (erroneous) returned value, but now some change in the headers makes
it fail. In other words, the weird behavior of %ENV may have let the script
run with the misspelled hash key. I'll give it a try this afternoon.

Thanks, RR
