The setup of %ENV is a convenience for CGI programmers. In fact, other than
loading/caching scripts, most of what Apache::Registry does is emulate the
CGI environment by setting up the %ENV hash and STDIN/STDOUT.
But the information that is placed into %ENV is all copied from the request
record (which is normally not available to CGI scripts), e.g.:
sub handler {
my $r = shift;
# $ENV{REMOTE_ADDR}
print $r->connection->remote_addr;
# $ENV{DOCUMENT_ROOT}
print $r->document_root;
# $ENV{REQUEST_URI}
print $r->uri;
}
These methods are all documented in the various mod_perl/Apache::*, plus the
guide, plus the Quick Reference card lists them.
Hope this helps!
