If it needs to be done "very very early" I tend to use PerlInitHandler which translates to either PostReadRequestHandler if in the configuration files, or PerlHeaderParserHandler if in a post-trans location, like an .htaccess file. Both of those are as soon as possible in that phase.

However, if you already have a PerlTransHandler, you can just drop this code into it: 

use Apache::Constants qw(REDIRECT); # if you don't already have it
sub handler {
  my $r = shift; # normal {grin}
  ...
  if (detect your cookie here) {
    $r->header_out(Location => "http://web.stonehenge.com/perltraining
+/");
    return REDIRECT;
  }
  ...
}

I don't play much with cookies, so I don't have any examples of detecting the cookie, but I presume you do. {grin} Oh yeah, and change that sample URL unless you want them to Learn some more Perl from some Experts. {grin} </code>
