自定义错误页面未显示

Question

出于某种原因,当我收到ASP.NET运行时错误时,它没有加载我的自定义错误页面

<customErrors mode="On" defaultRedirect="app_offline.htm" redirectMode="ResponseRewrite">
    <error statusCode="404" redirect="app_offline.htm"/>
        <error statusCode="500" redirect="app_offline.htm"/>
</customErrors>

那是在我的web.config中.

我仍然得到这个,但它没有加载我的错误.htm页面:

Server Error in '/' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>


Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>

我很确定app_offline.htm是ASP.NET中的保留文件名,如果存在于服务器上,它将始终提供.

尝试将其重命名为error.htm并更新您的<customErrors />块以匹配.
