我的MVC3应用程序显示403、404和500状态代码的自定义错误页面，但是浏览到trace.axd显示以下YSOD:
Server Error in '/' Application.
Trace Error
Description: Trace.axd is not enabled in the configuration file for this application. Note: Trace is never enabled when <deployment retail=true />
Details: To enable trace.axd, please create a <trace> tag within the configuration file located in the root directory of the current web application. This <trace> tag should then have its "enabled" attribute set to "true".
<configuration>
<system.web>
<trace enabled="true"/>
</system.web>
</configuration>
所以我禁用了跟踪功能，这很好，但是为什么不显示500页，因为这是从服务器返回的403？我真的很满意404、403或500，只要它不是一个丑陋的黄色屏幕!
编辑:在localhost上运行时，我与YSOD一起获得了500，但实际上它是服务器上的403，与我期望的更接近-但仍然没有自定义错误页面。服务器上的标准错误页面也略有不同:
Server Error in '/' Application.
Trace Error
Description: The current trace settings prevent trace.axd from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable trace.axd to be viewable on remote machines, please create a <trace> tag within the configuration file located in the root directory of the current web application. This <trace> tag should then have its "localOnly" attribute set to "false".
<configuration>
<system.web>
<trace localOnly="false"/>
</system.web>
</configuration>
最佳答案
按照@Cosmologinaut的建议删除IgnoreRoute对我不起作用，正如他所说的那样。我找到了一个更好的解决方案，该解决方案是删除Web.config文件中的跟踪HTTP处理程序:
<system.webServer>
<!-- remove TraceHandler-Integrated - Remove the tracing handlers so that navigating to /trace.axd gives us a
404 Not Found instead of 500 Internal Server Error. -->
<handlers>
<remove name="TraceHandler-Integrated" />
<remove name="TraceHandler-Integrated-4.0" />
</handlers>
</system.webServer>
现在导航到/trace.axd会给我们一个404 Not Found而不是500 Internal Server Error。
