I get a callback from a checkout server (Mal’s E-commerce) which includes GET data (used to calculate shipping) in the URL.
1. Checkout server redirects the client to a /shipping/ script on my server, including query string data.
2. Checkout server redirects to a script on my server which checks and converts the query string data into POST (form) data which is the ‘submitted’ to the /shipping/ script.
Or maybe I’m overcomplicating it? The aim is for the client not to see all the data in the query string when reaching the /shipping/ page on our server. I’m fairly certain that I can’t ask the other server to POST instead BTW.
