[Web-SIG] how to post from a cgi script and not a html form??

[Jeff Peery]

Thanks, thats a big help!
   
  only two things I don't understand well. when I create a http object with HTTPConnection() do I want this to be to my web host server (hostway.com) or to the server I'm posting to (authorize.net)?
   
  and what are the headers used for?
   
  again, thanks!
