Windows Server 2008 R2 (VPS) 上的 IIS7.5 - POST 请求出现错误 400
[英]IIS7.5 on Windows Server 2008 R2 (VPS) - Error 400 on POST Request
问题描述
I have a new VPS server running 2008 R2 and IIS 7.5.
我有一个运行 2008 R2 和 IIS 7.5 的新 VPS 服务器。
Some client software (not browser) communicates with a server application (ASP.NET) via HTTP GET and POST requests.一些客户端软件（不是浏览器）通过 HTTP GET 和 POST 请求与服务器应用程序 (ASP.NET) 通信。
On IIS7.5 the HTTP POST requests are rejected with the error: "HTTP Error 400 - Request is badly formed"在 IIS7.5 上，HTTP POST 请求被拒绝并出现错误：“HTTP 错误 400 - 请求格式错误”
The same application works with no issues on IIS7 and has worked for years on IIS6.相同的应用程序在 IIS7 上运行没有问题，并且在 IIS6 上运行了多年。
I can only assume IIS7.5 does some additional validation checks?我只能假设 IIS7.5 做了一些额外的验证检查？ Is there any way to turn them off?有什么办法可以关闭它们吗？ I tried all the settings I found on MSDN but nothing seems to work so far and I cannot even get IIS to dump a log for the rejected requests!我尝试了在 MSDN 上找到的所有设置，但到目前为止似乎没有任何效果，我什至无法让 IIS 为被拒绝的请求转储日志！
Changing the client code is not an option.更改客户端代码不是一种选择。
Below is the POST Request that fails.下面是失败的 POST 请求。

The problem is your Accept-Encoding: header.问题是您的Accept-Encoding: header。 The last two Content-Codings are not valid:最后两个内容编码无效：
application/octet-stream application/x-www-form-urlencoded
According to IANA's permissiable Content-Coding values you can only use:根据 IANA 允许的内容编码值，您只能使用：
compress deflate exi gzip indentity pack200-gzip
Hypertext Transfer Protocol (HTTP) Parameters - IANA
IIS7.5 adhere's more rigorously to the standards than previous versions. IIS7.5 比以前的版本更严格地遵守标准。
