I have a page at /form.php which POSTs to /results.php and on the /results.php page, there is an anchor link to goto the /payment.php page.
When someone clicks the back button on /payment.php it goes to /results.php showing
Confirm Form Resubmission This webpage requires data that you entered earlier in order to be properly displayed. You can send this data again, but by doing so you will repeat any action this page previously performed. Press the reload button to resubmit the data needed to load the page.
How do I show a cached version of the previous page i.e., the /results.php page ?
Using PHP not using any framework.
