Append Submission Data to URL Forward.

This is a great little article in general about how the GET method of form submission sends form submission data appended to the URL and our URL Forward option in the Confirmation Settings for a form gives you the option to “Append Submission Data to URL”.  The URL that you forward your user to can be a page with .PHP code that will do whatever you program that page to do with the appended data.  It is a best practice to forward only to Encrypted SSL Pages that start with an HTTPS:// rather than just an HTTP:// at the beginning of the web address.  The page on which the form is embedded does not necessarily need to be an HTTPS:// page, but it is always better to use an SSL.
