I have an XHTML page which is called after a successful credit card payment. But when the user hits the back button, he's charged again. How can I handle the issue, by either disabling the back button or invalidating his session when he hits back space or back button.

我正在使用Spring3/JSF，但是此问题与本参考文件无关，因为这是浏览器问题.

推荐答案

那是错误的设计.不要试图操纵客户做坏事-防止客户能够做坏事.

Thats the wrong design. Don't try to manipulate the client from doing bad things - prevent the client from being able to do bad things.

在这种情况下，为每个交易使用唯一的令牌，这样，如果用户单击并重新提交交易，交易将被拒绝，并可以通知用户交易已经通过.

Case in point, use a unique token for each transaction so that if the user clicks back and resubmits the transaction it will be rejected and the user can be notified that the transaction has already gone through.
