Is global.asax Application_Error event not fired if custom errors are turned on?
提问by jcvandan
If you have custom errors set to RemoteOnlyin web config - does this mean that MVC's application level error event in global.asax- Application_Erroris not fired on error?
如果您RemoteOnly在 web 配置中设置了自定义错误- 这是否意味着 MVC 的应用程序级错误事件global.asax-Application_Error不会因错误而触发？
I have just noticed that when a certain error occurs in my application, and I am viewing the site remotely, no error is logged. However, when I am accessing the app on the server and the same error occurs, the error is logged.
我刚刚注意到，当我的应用程序中出现某个错误并且我正在远程查看站点时，没有记录任何错误。但是，当我访问服务器上的应用程序并发生相同的错误时，会记录该错误。
this is the custom errors config setting:
这是自定义错误配置设置：
<customErrors defaultRedirect="/Error/Application" mode="RemoteOnly">
<error statusCode="403" redirect="/error/forbidden"/>
<error statusCode="404" redirect="/error/notfound"/>
<error statusCode="500" redirect="/error/application"/>
</customErrors>

Just out of interest for people - I ended up completely turning off custom errors and dealing with redirection in Application_Errorlike so:
只是出于人们的兴趣 - 我最终完全关闭了自定义错误并Application_Error像这样处理重定向：
protected void Application_Error(object sender, EventArgs e)
{
Exception exception = Server.GetLastError();
// ... log error here
var httpEx = exception as HttpException;
if (httpEx != null && httpEx.GetHttpCode() == 403)
{
Response.Redirect("/youraccount/error/forbidden", true);
}
else if (httpEx != null && httpEx.GetHttpCode() == 404)
{
Response.Redirect("/youraccount/error/notfound", true);
}
else
{
Response.Redirect("/youraccount/error/application", true);
}
}

If you do not call Server.ClearError or trap the error in the Page_Error or Application_Error event handler, the error is handled based on the settings in the section of the Web.config file.
如果您不调用 Server.ClearError 或在 Page_Error 或 Application_Error 事件处理程序中捕获错误，则会根据 Web.config 文件部分中的设置处理错误。
