Subject: net/http - Confirming the right implementation

Hey folks, I am trying to use net/http and net/https to implement a 
specific POST call for youtube's video upload service (am trying to use 
the direct upload API) and am looking to confirm that I am implementing 
the net/http library properly to do this.  The full POST call is as 
follows (this comes from the youtube API):

POST /feeds/api/users/default/uploads HTTP/1.1
Host: uploads.gdata.youtube.com
Authorization: ClientLogin auth=my_auth_token_here
X-GData-Key: key=my_dev_id_here
Slug: videofilename.mpg
Content-Type: multipart/related; boundary="f93dcbA3"
Content-Length: 1941255
Connection: close

--f93dcbA3
Content-Type: application/atom+xml; charset=UTF-8

<?xml version="1.0"?>

--f93dcbA3
Content-Type: video/mp4
Content-Transfer-Encoding: binary

--f93dcbA3--




Here is the code I am using to implement this, am hoping to make sure 
that I am using net/http correctly to pass all of the data where it 
needs to be.

dev_id = 'my_YT_dev_id_here'
upload_host = 'uploads.gdata.youtube.com'
upload_path = '/feeds/api/users/my_username_here/uploads'


youtube_direct_upload( upload_host, upload_path,  dev_id, video )


def youtube_direct_upload( host, path, dev_id, token, video )
   data = <<"DATA"
--f93dcbA3
Content-Type: application/atom+xml; charset=UTF-8

<?xml version="1.0"?>
<entry xmlns="http://www.w3.org/2005/Atom"
  xmlns:media="http://search.yahoo.com/mrss/"
  xmlns:yt="http://gdata.youtube.com/schemas/2007">

</entry>
--f93dcbA3
Content-Type: video/mpg
Content-Transfer-Encoding: binary

#{video}
--f93dcbA3--
DATA


   http = Net::HTTP.new( host, 443 )
   http.use_ssl = true

   headers = {
     'Host' => "#{host}",
     'Authorization' => "GoogleLogin auth=#{token}",
     'X-GData-Key' => "key=#{dev_id}",
     'Slug' => 'videofile.mpg',
     'Content-Type' => 'multipart/related; boundary="f93dcbA3"',
     'Content-Length' => data.length.to_s,
     'Connection' => 'close'
   }

   resp, data = http.post( path, data, headers )

   puts 'Code: ' + resp.code
   puts 'Data: '
   puts data

end



I left out the code which rerieves the auth_token from the youtube 
server as I have tested that aspect and it works fine, only having 
trouble getting the above to work, when I try it I get this string of 
errors:

/usr/local/lib/ruby/1.8/openssl/buffering.rb:178:in `syswrite': Broken 
pipe (Errno::EPIPE)

        from /usr/local/lib/ruby/1.8/net/http.rb:840:in `post'
        from youtube_auth.rb:95:in `youtube_direct_upload'


I am hoping that I have simply implemented the net/http library 
incorrectly, but am not sure... Any help would be greatly appreciated.

Thanks,
Andy
