问题描述
我碰上的 500 - 内部服务器错误在 PUT / DELETE 与Windows 2008服务器IIS。我得到的回应是：
I run into 500 - Internal Server Error when PUT/DELETE with windows 2008 server IIS. The response I get is:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"/>
<title>500 - Internal server error.</title>
<style type="text/css">

</style>
</head>
<body>
<div id="header"><h1>Server Error</h1></div>
<div id="content">
<div class="content-container"><fieldset>
<h2>500 - Internal server error.</h2>
<h3>There is a problem with the resource you are looking for, and it cannot be displayed.</h3>
</fieldset></div>
</div>
</body>
</html>
当我检查我的WebAPI的我的自定义日志，我发现电话一直没有连打服务。
When I check my custom logs of my WebAPI I find that the call has not even hit the service.
我以往的经验中得到的 404 - 找不到为 PUT 和删除和这种行为是在整个的Win7和Win 2008服务器是一致的。对于<一个href=\"http://stackoverflow.com/questions/10099270/asp-net-web-api-returns-404-for-put-only-on-some-servers\">I发现这个修复：
My earlier experience was getting 404 - Not Found for PUT and DELETE and this behavior was consistent across Win7 and Win 2008 Server. For that I found this fix:
我申请的修复和 PUT / DELETE 在WIN2008服务器部署在IIS 7相同的服务时，在Windows 7但在那之后的作品我没有得到400.但是，我得到的500 - 内部服务器错误从IIS甚至之前的东西。
I applied the fix and PUT/DELETE works on windows 7. But after that when deployed the same service on IIS 7 in win2008 server I do not get 400. But I get "500 - Internal Server Error" from IIS or something even before that.
同样的code完美的作品在Windows 7（IIS 7.5）。
The same code works perfectly on windows 7 (IIS 7.5).
对这类问题的解决任何线索？
Any clues on resolution of such issues?
编辑2012年8月29日：
500内部服务器错误的问题是通过使故障跟踪IIS7中检测到。解决方法是该配置。
The issue of 500-Internal Server Error is detected by enabling fault-tracing in IIS7. The fix is this configuration.
<modules runAllManagedModulesForAllRequests="true">
<remove name="WebDAVModule" />
</modules>
<handlers>
<remove name="WebDAV" />
</handlers>
基本上，我们需要从模块的处理程序删除WebDAVModule，也删除的WebDAV。但现在，我回到我的老问题 404-未找到。现在，即使有下面的配置我不能让建成后/ DELETE工作：
Basically we need to remove "WebDAVModule" from modules and also remove "WebDAV" from Handlers. But now I am back to my old issue of 404-Not Found. Now even after having the below configuration i cannot get PUT/DELETE to work:
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*" verb="GET,HEAD,POST,DEBUG,PUT,DELETE" type="System.Web.Handlers.TransferRequestHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />
不寻常的同一Web应用程序完美的作品上的同一系统相同的IIS托管分开（不在默认网站）。所以我怀疑这是由于它过滤PUT / DELETE请求一些家长的网站配置。
Unusually the same web application works perfectly on hosted separately (not under default web site) on the same system same IIS. So I suspect this is due to some parent website configuration which filters PUT/DELETE requests.
在相同的任何想法？
推荐答案
苦苦思索一个非常类似的问题后，我来到这个解决方案：
的http://www.iis.net/configreference/system.webserver/security/requestfiltering/verbs
After agonizing over a very similar problem, I came upon this solution: http://www.iis.net/configreference/system.webserver/security/requestfiltering/verbs
使用请求筛选设置，我能够在全球范围内允许PUT和IIS，这解决了我的问题DELETE动词。它结束了我404.6错误的噩梦。 （顺便说一句，我没有安装WebDAV和没有添加动词的ExtensionlessUrlHandler）
Using the Request Filtering settings, I was able to globally allow the PUT and DELETE verbs in IIS, which solved my problem. It ended my nightmare of 404.6 errors. (btw, I did not have webDAV installed and did add the verbs to the ExtensionlessUrlHandler)
希望这个信息能节约一些时间。
Hopefully this info can save someone some time.
