Hi,
I use header("Cache-Control: private");
to prevent page expiry problem. It is to make browser’s “Back” button work otherwise; page expires if user hits “Back” button to go back and see previous pages.
I have 3 steps buying process.
1. Delivery address selection from radio boxes
2. Creadit card details is typed into textbox etc.
3. Confirmation page with “Confirm” button
When it is confirmed, I want these 3 pages unavailable when “Back” is clicked by users.
How can I do it?
Thanks
