I need to construct a response string using the old html_out that calls a post method on a remote server. In other words, I need to format a return page that is the equivalent of a post method submit form (without requiring a submit button to be pressed by the user)

 

I Know that the ContentType = "application/x-www-form-urlencoded" should be in the beginning of the return string. Can someone point me to the information on how this return string should look?
