Getting 301 Error when making HTTP GET Requests using C++ sockets

I am trying to make GET requests from a C++ program and every time I get a 301 Moved Permanently error. I am using an API that uses sockets and cannot seem to figure out why this error always comes up.

Here is the request that is getting made: 

GET https://www.quandl.com/api/v3/datasets/EOD/AAPL.csv?sort_order=asc&auth_token=YZffVEztoepdzHNAMexz HTTP/1.1
Host: www.quandl.com
Connection: close

And here is the response to the request: 

HTTP/1.1 301 Moved Permanently
Date: Sun, 12 Nov 2017 03:58:41 GMT
Content-Type: text/html
Content-Length: 182
Connection: close
Set-Cookie: __cfduid=d51b8e22f5239ed65b480d8ec37cad8251510459121; expires=Mon, 12-Nov-18 03:58:41 GMT; path=/; domain=.quandl.com; HttpOnly
Location: https://www.quandl.com/api/v3/datasets/EOD/AAPL.csv?sort_order=asc&auth_token=YZffVEztoepdzHNAMexz
Server: cloudflare-nginx
CF-RAY: 3bc6930581840ed9-EWR

<html>
<head><title>301 Moved Permanently</title></head>
<body bgcolor="white">
<center><h1>301 Moved Permanently</h1></center>
<hr><center>openresty</center>
</body>
</html>

I think it may have to do with the Http-only part in the Set-cookie but am not 100% sure about that and don't know how to get rid of it. I think the url in the response after location is where the page has "moved to", however it is the exact same one as the one I am requesting so I don't understand why I am getting the error.

301 isn't an error, it means the resource has changed URL's.

When you get this valid response code you can issue another request to the Location URL specified in the response.

Be careful to limit the number of times you follow a redirect because you could wind up with an infinite loop. A lot of HTTP client libraries have an option to handle this automatically.

That's not a valid request for a https:// resource. Instead you have to create a TLS connection to the server (instead of only a TCP connection) and send the request with path-only instead of full-URL:

GET /api/v3/datasets/EOD/AAPL.csv?sort_order=asc&auth_token=YZffVEztoepdzHNAMexz HTTP/1.1
Host: www.quandl.com
Connection: close
