Question

Hello I am trying to do a redirect if the response is a 404 but it is not working as expected, can you experts see the issue?. It still goes to the generic 404

in my Global.asax

protected void Application_BeginRequest(Object sender, EventArgs e)
{
       if (Response.Status == "404 Not Found")
        {
            string notFound = "~/custom_notfound.aspx";
            Response.Redirect(notFound);
        } 

}

UPDATE

Tried so far

(Response.Status == "404 Not Found")
(Response.Status == "404")
(Response.StatusCode == 404)

You can also use the web.config customerrors section – as shown here

e.g. In the system.web section,

<customErrors mode="On" defaultRedirect="/custom_error.aspx">
    <error statusCode="404" redirect="/custom_notfound.aspx" />
</customErrors>
