Question

My app currently uses OAuth to communicate with the Twitter API. Back in December, Twitter upped the rate limit for OAuth to 350 requests per hour. However, I am not seeing this. I am still getting 150 from the account/rate_limit_status method.

I was told that I needed to use the X-RateLimit-Limit HTTP header to get the new rate limit. However, in my code, I do not see that header.

Here is my code…

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(newURL);
request.Method = "GET";
request.ServicePoint.Expect100Continue = false;
request.ContentType = "application/x-www-form-urlencoded";

using (WebResponse response = request.GetResponse())
{
    using (StreamReader reader = new StreamReader(response.GetResponseStream()))
    {
        responseString = reader.ReadToEnd();
    }
}

If I inspect the response, I can see that it has a property for Headers, and that there are 16 headers. However, I do not have X-RateLimit-Limit in the list.

Any idea what I am doing wrong?

Look at the raw response text (e.g., with Fiddler). If the header isn’t there, no amount of C# code is going to make it appear. 🙂 From what you’ve shown, it seems the header isn’t in the response.

Update: When I go to: http://twitter.com/account/rate_limit_status.xml there is no X-RateLimit-Limit header. But when I go to http://twitter.com/statuses/public_timeline.xml, it’s there. So I think you just need to use a different method.

It still says 150, though!
