title: Cannot Set Status Code
body: <p>I'm using the basic <code>Response.StatusCode</code> to set the status code to 9999. This page is being called via an AJAX call, checking the status code on <code>readyState = 4</code> and popping an alert on 9999 using the message set by <code>Response.StatusDescription</code>. All I'm getting is <code>readyState = 4</code> and <code>statusCode = 200</code>. I can provide code if needed, but it's not trim, so I'll trim it down if the code is needed/requested. Any help is appreciated.Coded in C# ASP.NET and Javascript.</p>
  
  <p><strong>UPDATE</strong> <em>Purpose:</em> I'm suing the status code 9999 to denote a "User already exists" error when adding a user to an SQL table. This is the only way I can find to let the AJAX call know when this error occurs.</p>
