307内部重定向的一个很好的例子是当谷歌Chrome遇到一个HTTP调用到一个域，它知道需要严格的传输安全。

浏览器使用与原始调用相同的方法无缝重定向。

另外，对于服务器管理员，重要的是要注意，如果使用307重定向，浏览器可能会向用户显示提示。

例如，Firefox和Opera会要求用户允许重定向，而Chrome、IE和Safari会透明地进行重定向。

在某些用例中，攻击者可能会滥用307重定向来了解受害者的凭据。

上述论文的作者建议如下:

Fix. Contrary to the current wording in the OAuth standard, the exact method of the redirect is not an implementation detail but essential for the security of OAuth. In the HTTP standard (RFC 7231), only the 303 redirect is defined unambigiously to drop the body of an HTTP POST request. All other HTTP redirection status codes, including the most commonly used 302, leave the browser the option to preserve the POST request and the form data. In practice, browsers typically rewrite to a GET request, thereby dropping the form data, except for 307 redirects. Therefore, the OAuth standard should require 303 redirects for the steps mentioned above in order to fix this problem.

307和302之间的唯一区别是307保证在重定向请求发出时方法和主体不会被更改。对于302，一些旧客户端错误地将方法更改为GET:使用非GET方法和302的行为在Web上是不可预测的，而使用307的行为是可预测的。对于GET请求，它们的行为是相同的。

301: permanent redirect: the URL is old and should be replaced. Browsers will cache this. Example usage: URL moved from /register-form.html to signup-form.html. The method will change to GET, as per RFC 7231: "For historical reasons, a user agent MAY change the request method from POST to GET for the subsequent request." 302: temporary redirect. Only use for HTTP/1.0 clients. This status code should not change the method, but browsers did it anyway. The RFC says: "Many pre-HTTP/1.1 user agents do not understand [303]. When interoperability with such clients is a concern, the 302 status code may be used instead, since most user agents react to a 302 response as described here for 303." Of course, some clients may implement it according to the spec, so if interoperability with such ancient clients is not a real concern, 303 is better for consistent results. 303: temporary redirect, changing the method to GET. Example usage: if the browser sent POST to /register.php, then now load (GET) /success.html. 307: temporary redirect, repeating the request identically. Example usage: if the browser sent a POST to /register.php, then this tells it to redo the POST at /signup.php. 308: permanent redirect, repeating the request identically. Where 307 is the "no method change" counterpart of 303, this 308 status is the "no method change" counterpart of 301.

RFC 7231(从2014年开始)可读性很强，不会过于冗长。如果你想知道确切的答案，这本书是推荐阅读的。其他一些答案使用了1999年的RFC 2616，但没有任何变化。

RFC 7238指定308状态。它被认为是实验性的，但在2016年已经被所有主要浏览器支持。
