如何显示结果所以后退按钮不要求重新加载POST变量

Question

I have a form that uses XML to get results. From those results users can click to a detail page. My problem is when a user clicks back to the results page, they are asked if they want to submit the form again. How do I create this so back button just displays the results, like on aa.com, ebay, autotrader, etc.

Thanks!

When you submit your page move the $_POST variables into the $_SESSION array and then header redirect the user to the results page.
