=head1 SYNOPSIS

  # If $env is like followings:
  # $env->{PATH_INFO}       = '/mysite/user/hkoba'
  # $env->{PATH_TRANSLATED} = '/var/www/webapps/mysite/html/user.yatt/hkoba'

  # $con should be created like this:
  my $con = YATT::Lite::WebMVC0::Connection->create(
               $parent_fh,
               env => $env,

               site_prefix => "/mysite",

               dir         => "/var/www/webapps/mysite/html",
               location    => "/",
               file        => "user.yatt",
               subpath     => "/hkoba",

               # cgi => Plack::Request->new($env),
               # no_nested_query => 1
            );

  # or

  $con = $siteapp->make_connection($parent_fh, @config);

  # Connection is just a blessed glob handle

  print $con "foo", "bar";
  my $result = $con->buffer; # "foobar";

  # Connection can carry request specific values such as parameters.
  my $val = $con->param('x') + $con->param('y');
  $con->stash->{'foo'} = 3;


  # Connection implements YATT::Lite::Object like configure/cget methods.
  print $con->cget('env');
  $con->configure(dir => $foo, file => $bar);


  $con->redirect($url, $params);

  $con->error("Found error in %s!", $path);
  # $con->raise(error => "Found error in %s!", $path);
