=head1 NAME
Apache::TestHandler - a few response handlers and helpers
=head1 SYNOPSIS
    package My::Test;
    use Apache::TestHandler ();
    sub handler {
        my ($r) = @_;
        my $result = do_my_test;
        Apache::TestHandler::ok1 $r, $result;
    }
    sub handler2 {
        my ($r) = @_;
        my $result = do_my_test;
        Apache::TestHandler::ok $r, $result;
    }
=head1 DESCRIPTION
C<Apache::TestHandler> provides 2 very simple response handler.
=head1 FUNCTIONS
=over 4
=item ok $r, $boolean
The handler simply prints out C<ok> or C<not ok> depending on the
optional C<$boolean> parameter.
If C<$boolean> is omitted C<true> is assumed.
=item ok1 $r, $boolean
This handler implements a simple response-only test. It can be used on its
own to check if for a certain URI the response phase is reached. Or it
can be called like a normal function to print out the test result. The
client side is automatically created as described in
L<http://perl.apache.org/docs/general/testing/testing.html#Developing_Response_only_Part_of_a_Test>.
C<$boolean> is optional. If omitted C<true> is assumed.
=item same_interp_counter
=item same_interp_fixup
