Question about custom errors.

[Ranv]

Is it possible to use web.config to handle 404 Page Not Found errors,
and application level custom errors (in global.asax) to handle all
other errors? I suppose I would have to make sure that I don't call
Context.ClearError(); when a 404 Error occurs, but how do I check in
code that this has occured?

What I have right now in global.asax is:

protected void Application_Error(object sender, EventArgs e)
{
Response.Write( Server.GetLastError().ToString() );
Context.ClearError();
}

I've set up web.config to handle 404 errors, but when they occur, the
function in global.asax handles them instead. Hopefuly someone can
help. Thanks in advance.
