=head1 NAME

Apache::FakeRequest - fake request object for debugging

=head1 SYNOPSIS

    use Apache::FakeRequest;
    my $request = Apache::FakeRequest->new(method_name => 'value', ...);


=head1 DESCRIPTION

B<Apache::FakeRequest> is used to set up an empty Apache request
object that can be used for debugging.  The B<Apache::FakeRequest>
methods just set internal variables of the same name as the method and
return the value of the internal variables.  Initial values for
methods can be specified when the object is created.  The I<print>
method prints to STDOUT.

Subroutines for Apache constants are also defined so that using
B<Apache::Constants> while debugging works, although the values of the
constants are hard-coded rather than extracted from the Apache source
code.

    #!/usr/bin/perl

    use Apache::FakeRequest ();
    use mymodule ();

    my $request = Apache::FakeRequest->new('get_remote_host'=>'foobar.com');
    mymodule::handler($request);
