什么可以导致IIS接收HTTP动词"2GET"

Question

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

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

正如我所说,大多数时候链接成功执行.然而,非常偶然的用户已被满足:

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

这似乎是报告用户的浏览器使用动词2GET提交了请求.怎么会这样？

通过我们的测试服务器上的日志,我可以看到此问题的一些其他实例:

我们正在IIS7上运行.

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

更新:我得到各种奇怪的动词:2GET,9GET,1POST,5POST ......

Answer 1

此请求格式错误 GET 请求来自浏览器端。您可以将错误定位到 IP 192.168.202.204。

它不是IIS或你的服务器，它不是网卡（TCP有纠错）。

可能是浏览器有问题，或者该机器上有一些代理/防火墙拦截 http 流量。也有可能是病毒。但是，正如我所见，它是在客户端。
