我有一个用户在单击我的应用程序中的链接时间歇性地收到 HTTP 405。据我所知，链接没有什么好笑的......

<a id="ctl00_ctlNavigationMenu_viewTransfersLink" href="Navigate.ashx?target=6">- View Transfers</a>

正如我所说，大多数情况下链接都会成功执行。但是，用户偶尔会遇到：

405 - 不允许用于访问此页面的 HTTP 动词。

当我检查 IIS 日志时，我可以看到以下条目：

2009-02-04 15:12:50 192.168.202.204 2GET /Navigate.ashx target=6 80 - 192.168.202.141 Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+1.1.4322;+InfoPath.2;+.NET+CLR+2.0.50727) 405 0 1 13203

这似乎是在报告用户的浏览器已使用动词2GET提交了请求。怎么会这样？

查看我们测试服务器上的日志，我可以看到这个问题的其他一些实例：

我们在 IIS7 上运行。

有任何想法吗？2GET 作为动词存在吗？它可以与我表单上的 UpdatePanel 相关吗？

沙

更新：我得到了各种奇怪的动词：2GET、9GET、1POST、5POST ......

This request is malformed GET request is coming from the browser side. And you can pinpoint error to IP 192.168.202.204.

It is not IIS or your server, it is not network card (TCP has error correction).

It can be that browser is buggy or that there is some proxy / firewall on that box that interceps http trafic. Could be the virus too. But, as I see, it's on the client side.

如果您有权访问客户端计算机，请在其上运行 Wireshark 以捕获流向您的服务器的流量。您还应该在服务器上运行 Wireshark 并过滤来自该 IP 地址的流量，以排除 IIS 中的问题（不太可能。）

了解线路上发生了什么可以帮助您缩小问题所在的范围。最有可能的是，您会看到靠近浏览器的流量看起来还不错，并且在到达服务器的途中被某些东西破坏了，但至少您可以缩小可能的嫌疑人的较小列表。

Very odd indeed.

  • Is this only occurring from one computer?
  • Are these requests coming directly from the user's computer, via a proxy, or perhaps via ISA Server?
  • Is it an option to install IEHttpHeaders onto the problem browser and monitor the HTTP headers from that end?
