Application_Error event and 404 error?

[Stoyan]

I implemet in Application_Error event in Global.asax, So now when some error
occurs in application it send me email, the problem is that it consider 404
like error and send me everytime email when some user type some wrong
address of page.

Is it possible to filter the error code? Can I in Application_Error event
check if error is 404 and do not send email?



thanks
