火狐发送请求两次 [英] Firefox sending request twice

问题描述

我试图处理信用卡交易在.NET和它完美的作品在Safari，Opera和IE浏览器。当我尝试在Firefox发送两个请求相同的事务，我结束了一个双重收费卡。从对谷歌快速搜索似乎这是一个问题与萤火虫，但我无法找到一个方法来阻止这种双重职务。

I'm trying to process a credit card transaction in .net and it works perfectly in Safari, Opera, and IE. When I try the same transaction in Firefox it sends two requests and I end up with a double charged card. From a quick search on Google it seems that this is an issue with Firebug but I am unable to find a way to stop this double post.

有没有人有任何想法如何从这样prevent火狐（和萤火虫）？

Does anyone have any idea on how to prevent Firefox (and Firebug) from doing this?

推荐答案

使用的现时 ，一个独特的键是只使用一次。

Use a nonce, a unique key which is only used once.

发送与表单字段到浏览器的唯一编号（这往往是一个隐藏的输入字段进行），并保存副本的服务器与交易上。在窗体，更改提交的数量。验证该密钥匹配处理您的请求时。

Send a unique number along with the form fields to the browser (this is often done with a hidden input field), and store a copy on the server with the transaction. Within the form, change the number on submit. Validate that the keys match when processing your requests.

也可能会发生的事情在前端一个明确的解释，这个问题是可以消除客户端。这是最好的解决服务器上的双提交的问题，只是因为有这么多的方法，使双提交可能发生。

There may also be a clear explanation of what's happening on the front end, and that issue could be eliminated client-side. It's best to solve the double-submit problem on the server, simply because there are so many ways in which a double submit could occur.
