Unable to Update the Status Code

When it comes to setting the status code to 9999, I am utilizing the basic Response.StatusCode. In this case, the page is accessed via an AJAX call and the status code is checked at readyState = 4. On detecting 9999 as the status code, an alert pops up with the message specified by Response.StatusDescription. However, despite my efforts, all I see is readyState = 4 and statusCode = 200. I can share code snippets if required, though I may need to trim them down. Any assistance in this regard would be greatly appreciated. Coded in C# ASP.NET and Javascript.

UPDATE Purpose: The reason behind using the status code 9999 is to indicate an "User already exists" error while attempting to add a user to an SQL table. This is currently the only method through which the AJAX call can detect the occurrence of such an error.

Answer №1

Creating status codes is not allowed. If you need valid ones, check out this list

In my opinion, the most effective approach is to return your status and message in a json response.

{
    status: 9999,
    message: "User already exists"
}

For more information on how to implement this, take a look at this Stack Overflow post: Returning JSON object from an ASP.NET page
