By default, it's part of your %ENV hash, stored as $ENV{HTTP_REFERER}.  
CGI.pm has builtin methods for accessing it -- if you've created a CGI
object as $q, then it's $q-> referer(). Generating a dump of the %ENV hash
will give you a list of the others you have access to -- generally 20 or
so properties for any given web transaction.
