In my web application I captured all unhanded exceptions by using the following method:

1)In web.config, add:
<customErrors mode="RemoteOnly" defaultRedirect="error.aspx" />

2)In global.asax.vb, add:
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
    ' Fires when an error occurs
Dim Mymessage As New MailMessage
SmtpMail.Send("[email protected]", "[email protected]", "Error occurs", Request.Path & Server.GetLastError.ToString())
End Sub

Everything works fine.

As far as I understand, the “RemoteOnly” is an option that only allows users who access the web application from the local machine (localhost) to see the exception information, while all other users will be redirected to the defaultredirect page (“error.aspx” in my case).

My web application is available to company’s intranet users as well as Internet users, how could I allow all users inside the company see the detailed exception information, and redirect all outside users to “error.aspx?

Could I possible detect the user’s IP address at this stage, then according to the use’s IP address to decide whether to redirect the user or not?

Any suggestions would be very appreciated.

Thank you!

Hi there,

AFAIK, RemoteOnly means "everything but localhost". This means all other computers will see the friendly error page, and only on localhost can you see the real error message.

Either way, Application_Error will fire, so you can do / check whatever you need to do inside that method.

Cheers,
