问题描述

我有一个iframe:

I have an iframe that:


  1. 向服务器发出过请求

  2. 302并设置Cookie

  3. 浏览器不保存Cookie,但发布信息(不知道为什么不获取,但不重要)

  4. #3失去了

  1. does a post request to server
  2. server returns 302 and sets cookie
  3. browser not saves cookies but does a post(don't know why not get but it doesn't matter)
  4. cookie from #3 are lost

我找到了一个解决方法:

i've found a workaround:

Response.AddHeader("Pragma", "no-cache");
Response.AddHeader("Cache-Control", "no-cache");

但它没有帮助。
mb任何人都知道什么可以解决这个问题?

but it didn't help. mb anybody knows what can fix this issue?

推荐答案

POST而不是GET,因为这意味着有一个重要的信息,你遗漏了。没有浏览器会使用POST 跟踪HTTP / 302重定向。

You may want to look into why your browser is doing a POST rather than a GET, since that implies that there's an important piece of information that you left out. No browser will follow a HTTP/302 redirect with a POST.

在IE9中,

In IE9, redirection responses are cached if headers allow (IE8 and below would not cache redirects).

您可以在302重定向上绝对设置一个cookie,而且重定向响应会被高速缓存,如果允许的话(IE8和以下不会缓存重定向)。这里有两种可能性:

You can absolutely set a cookie on a 302 redirect. There are two possibilities here:


  1. 您的Cookie被删除,因为您未能在响应中提供P3P标题,表明您的隐私权做法

  2. 您的重定向响应是从用户的缓存中提取的,而不是服务器,缓存的响应未设置Cookie。

鉴于您在IFRAME中遇到此问题,#1似乎更有可能。 (请参阅快速浏览P3P

Given that you're having this problem in an IFRAME, #1 seems more likely. (See Quick Look at P3P)
