  use HTTP::Request::FromTemplate;
  use LWP::UserAgent;

  my $ua = LWP::UserAgent->new();

  my $template = <<TEMPLATE

  TEMPLATE
  my $t = HTTP::Request::FromTemplate->new(template => $template);
  my $req = $t->process({ 'host' => 'apple.com',
                          'path' => '/',
                          'query' => '?',
                           });
  my $response = $ua->request($request); # replay the request

=head1 ABSTRACT

I wanted this for a long time already. It makes it very convenient
to just paste a logged session from the
L<Live HTTP Headers|http://livehttpheaders.mozdev.org/>
into a template file and be able to faithfully replay a request
or to parametrize it without needing to manually compare what
is sent against what I want.

=head1 PREDEFINED TEMPLATE PARAMETERS

There is one predefined/magic template parameter. C<content_length>
will be set to the length of the content (after the template has
been filled out) unless it was passed in via the template
parameters.

=head1 FEEDBACK

This is one of the modules that I created because the idea hit
me as crazy but useful. So if you use the module, please tell
me what enhancements you'd like, or where it falls short
of your expectations.

=head1 KNOWN BUGS

=over 4

=item * While this module tries to faithfully replicate a HTTP request
from a template, it uses L<HTTP::Request>. This means that the order
of the headers will be as L<HTTP::Request> thinks and not as your
template prescribes.

=item * Only rudimentary testing has been done.

=item * The test suite uses L<Test::Base>, which uses L<Spiffy>. I
know I will rot in hell for that, but it was so convenient at the time.

Patches are welcome.
