c# - System.Net.CookieException -- ... 超出配置的最大大小，即 '4096'

Question

我正在使用带有自定义安全框架的自定义 .Net 应用程序。除其他事项外，该框架使用户身份验证能够无缝传递到 SQL Server Reporting Services，以便在查看器中访问报告。但是，某些用户出现以下错误:

我已尝试根据一些建议(包括 http://www.iis.net/configreference/system.webserver/security/requestfiltering/requestlimits)更改应用程序以及 ReportServer 和 ReportManager 文件夹中的 web.config。和 http://bartwullems.blogspot.com/2010/04/uploading-large-files-in-iis-7.html

但是，我仍然收到错误消息，用户无法访问报告。还有什么我需要做的吗？谢谢。

Answer 1

1. 你都设置了吗？ http://forums.iis.net/t/1169846.aspx

2. 但是您得到的是 CookieException，而不是最大请求限制异常。以上设置与cookies无关。他们指的是文件上传到服务器。

3. 您似乎是想将超过 4K 的内容塞进 cookie。如果是这样，你不能..这是系统限制What is the maximum size of a web browser's cookie's key? ..实际上，您的里程可能因浏览器而异，但如果您在 cookie 中设置超过 4K，您可能需要改变策略，例如切换到 session 。

4. 对 N° 3 说是吗？您可以在此处更正错误..但您仍然可能会遇到问题 3 :-)

取自您自己的堆栈跟踪 这超过了配置的最大大小，即“4096”...在 System.Net.CookieContainer.Add(Cookie cookie) ...ReportServerProxy.cs:line 131

var container = new System.Net.CookieContainer {
    MaxCookieSize = 8192
};

container.Add(new System.Net.Cookie {
    Value = "somehugevalue"
});
