I've found many references to this while googling around, but no definite
answers. I'm wanting to get the refering page information in a perl/cgi
script and base the flow of the script on it. That is, if the request is
from a refering page that is 'authorized', the script continues on with it's
normal flow, but if the refering page is not authorized, the script will
exit. I've tried using the HTTP_REFERER variable, but in all cases it returns
an empty value regardless of the browser or the address the request
originates from. The old standard CGICount program seems to handle this
quite well, allowing only domains/pages entered in it's configuration to
access the counter, but this program is written in C and I don't see any
obvious correlations in it's source code that I can make sense of and try to
port over to Perl. Is there any other means of getting the referer
information other than through the $ENV{} variables?
Cheers,
Charles
