Using HTTP Post variables with multiple domains and scripts

Hi Folks, I use the regular form POST method to send variables from Domain A to Domain B. On domain B I run a short script. The script does it's thing and then sends the posted variables back to Domain A with header("Location: http://www.domainA.com/folder/script.php"); The problem is that the variables disappear at this point - after the domain B script is run - and do not appear to go any further. I have tried this code, which works: header("Location: http://www.domainA.com/folder/script.php?var1=foo&var2=bar"); ... but for security reasons I should not use the GET method for passing the originally posted variables. I do not want to stop the form post process, I just want to run my own script routine and then continue with the original form request. How do I accomplish the posting of variables from Domain A to Domain B and back again to Domain A without reposting them in an additional form post submission? Thanks!
