Easy ( i hope): Error handling

[eramgarden]

I added 2 kinds of error handling to my code:

 

In web.config , i have this

 

<customErrors  defaultRedirect="ApplicationError.htm" mode="RemoteOnly" >
    <error statusCode="403" redirect="pages\Forbidden.htm"/>
    <error statusCode="404" redirect="NotFound.htm"/>
   
   </customErrors>

 

In Global.asax , I have this to log to even viewer:

 

Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
       ' Fires when an error occurs
       Dim unhandledException As Exception = Server.GetLastError().InnerException
       If Not EventLog.SourceExists("ESPWebClient") Then
           EventLog.CreateEventSource("ESPWebClient", "ESPWebClient Log")
       End If

       Dim el As EventLog = New EventLog()
       el.Source = "ESPWebClient"
       el.WriteEntry("An exception occured: Created an entry in the event log")
       'Server.ClearError()

   End Sub

 

I got an unhandeled error, But instead of loging to event viewer, the Custom Error in WebConfig popped up

 

Why didnt the application error in Global.asax fire??

[fadi]

use either one of the ways, either remove the custom errors and place the redirections in global.asax or remove the application_error event

they both do the same job

[eramgarden]

they both do the same job ...

 

No, i think they're different...

 

The Application_Error takes care of overall Application unhandled errors... So i think in this case, i think application_error should've fired..

 

 

I'm still not sure why, how the custom error fired ??
