饼干过期不工作在C＃ [英] Cookies expiration not working in C#

问题描述

我试着用C＃4.0做一个永久性的Cookie，这code：

 的HttpCookie AssoCookie =新的HttpCookie（准code，副code）;
AssoCookie.Expires = DateTime.Now.AddMonths（6）;
HttpContext.Current.Response.Cookies.Add（AssoCookie）;
 

不幸的是，它不工作的cookie是会话届满。如果我使用Web开发的插件在Firefox来检查它，我可以看到这样的信息：

 名助理code
值测试
主机本地主机
路径    /
安全无
到期结束会话
 

我在做一个试验的cookie它只是在那里创建，否则没有人管理它或编辑它，所以它不能被覆盖。在webconfig设置Cookie到期我什么都没有设置（反正这应该重写），如果我设定了一些饼干过期时间是行不通的。

我现在有点失落，每一个手册，指南，博客，无论我查说，你只需要设置的过期日期，我已经调试，香港专业教育学院检查创建时，它确实具有价值和PAGE_年底preRender但它只是到期与会话无论我做什么。

任何想法？

即时通讯使用的是Firefox 9.0.1 BTW。

更新

在Firefox用Firebug插件来检查响应头，我得到这样的：

 响应Headersview源

和使用招我得到这样的：

**更新2 ** 林检查Cookie的犯规存在只是我的Firefox的饼干之间的检查，但是，如果你想看到我在code以后得到它（没有必要，因为它不是在那里反正）：

 尝试{
    副code = HttpContext.Current.Request.Cookies.Get（准code）的价值。
} 抓住 { }
 

解决方案

好了各位。我很抱歉，但似乎由于某种原因，我已经配置了我的浏览器前段时间删除cookie，当我关闭的窗口，所以，尽管得到适当创建的cookie的浏览器设置好的它们作为会话cookie，不是因为他们不过是因为浏览器选项。

事实上，如果我去了在Firefox中管理Cookie，我可以取消在cookie的选项会话Cookie，然后在截止日期是正确的，但由于某些原因，检查选项默认为选中。我想，也许有一种方式，如果一个Cookie是会话Cookie或没有，或者净是做什么，直到我意识到这一点来设置。

嗯，没事的时候逻辑似乎工作，你知道这个问题是最愚蠢的事，你能想象...

再次抱歉。

Im trying to make a persistent cookie using C# 4.0 and this code:

HttpCookie AssoCookie = new HttpCookie("AssociateCode", AssociateCode);
AssoCookie.Expires = DateTime.Now.AddMonths(6);
HttpContext.Current.Response.Cookies.Add(AssoCookie);

Unfortunately, it doesn't work and the cookie is session expiring. If I use Web Developer plugin in Firefox to check it I can see this info:

Name    AssociateCode
Value   test
Host    localhost
Path    /
Secure  No
Expires At End Of Session

The cookie I'm doing as a test its just created on there, noone else manages it or edits it so it cannot be overwritten. I have nothing set in webconfig to set cookies expiration (anyway this should override that) and if I set some cookies expiration time it doesnt work.

I'm a bit lost now, every manual, tutorial, blog, whatever I check says you just have to set the Expiration date, Ive debugged, Ive checked that it really has that value when created and at the end of Page_PreRender but it just expires with session whatever I do.

Any ideas?

Im using Firefox 9.0.1 btw.

Update

Using Firebug plugin in Firefox to check response headers I get this:

Response Headersview source
Cache-Control   private
Connection  Close
Content-Length  21322
Content-Type    text/html; charset=utf-8
Date    Mon, 23 Jan 2012 16:47:08 GMT
Server  ASP.NET Development Server/10.0.0.0
Set-Cookie  AssociateCode=test; expires=Mon, 23-Jul-2012 16:09:04 GMT; path=/
X-AspNet-Version    4.0.30319

And using Fiddler I get this:

HTTP/1.1 200 OK
Cache-Control: private
Content-Type: text/html; charset=utf-8
Server: Microsoft-IIS/7.5
X-AspNet-Version: 4.0.30319
Set-Cookie: AssociateCode=; expires=Mon, 23-Jul-2012 16:27:29 GMT; path=/
X-Powered-By: ASP.NET
Date: Mon, 23 Jan 2012 17:27:29 GMT
Content-Length: 21313

** Update 2 ** Im checking that the Cookie doesnt exist just checking between my Firefox's cookies, but, in case you want to see how I get it later in code (not necessary since it not on there anyway):

try {
    AssociateCode = HttpContext.Current.Request.Cookies.Get("AssociateCode").Value;
} catch { }

解决方案

Ok everybody. I am so sorry but it seems for some reason I had configured my browsers time ago to delete cookies when I closed windows, so, despite Cookies were being created properly the browser setted them as session cookies not because they were but because of browser options.

In fact, if I went to manage Cookies in Firefox, I could uncheck the option "Session Cookie" in a cookie and then the Expiration Date was the correct one, but for some reason that check option was checked by default. I thought that maybe there was a way to set if a Cookie is Session Cookie or not, or maybe .Net was doing something until I realized this.

Well, when nothing logic seems to work, you know the problem is the most stupid thing you could imagine...

Sorry again.
