Question

Most ajax frameworks seem to standardize with “X-Request-With” on either a header or the query string.

And in ASP.NET MVC you can use the extension method

Request.IsAjaxRequest()

Because an ajax client can request several different content types, not just “application/json” ex: “application/xml”.

I’m using the following code snippet/extension method, but I would love to see what others are doing or if there is something I missed, or a better way.

public static bool IsJsonRequest(this HttpRequestBase request)
{
    return request.Headers["Accept"].Split(',') 
       .Any(t => t.Equals("application/json", StringComparison.OrdinalIgnoreCase));
}

Thanks in advance.

Answer 1

Why cant you just pass a bool variable say IsJsonRequest from the client where you are making request?

Then make a check in action method.

or

You could use the request’s accept header for this. This indicates what type of content the client wants the server to send to it.
