重定向错误401.2未经授权

Question

I've been trying to redirect on Error message 401.2.: Unauthorized: Logon failed due to server configuration as per below:

<customErrors defaultRedirect="Error.aspx" mode="On">
      <error statusCode="401" redirect="Unauthorized.aspx" />
    </customErrors>

But it never actually redirects. It still displays the default Access is denied page. What am I doing wrong there?

Answer 1

Adding the below to global.asax seems to be working just fine:

void Application_EndRequest(object sender, EventArgs e)
        {
            if (Response.StatusCode == 401)
                Response.Redirect("Unauthorized.aspx");
        }

Answer 2

First Try this:

Set on your Unauthorized.aspx.cs Page_Load Method :

private void Page_Load(System.Object sender, System.EventArgs e)
{
    //Put user code to initialize the page here 
    Response.StatusCode = 401;
    Response.TrySkipIisCustomErrors = true;
}

See this for detail:

HttpResponse.TrySkipIisCustomErrors Property

IIS 7 Error Pages taking over 500 Errors

Second Try this: Use this in addition to tag to bypass the IIS Error page:

<system.webServer>
      <httpErrors existingResponse="PassThrough" />
</system.webServer>
