CURLOPT_FOLLOWLOCATION

I looked up google for more information. But the more I read, the more I am confused or wonder

I understand that CURLOPT_FOLLOWLOCATION() follows "the location", but what is the location? Is it the url that is initialized? 

  curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, false);

I only need to post data into icontact mailing list - so would this snippet above prevent the data from going in the mailing list?

I printed $result and see that the data went in the correct mailing list although I cannot see whether the data are the correct ones which are from form.

If you set CURLOPT_FOLLOWLOCATION to true (or 1), cURL will automatically follow these redirects. This means that if the server responds with a 3xx status code (e.g., 302 Found, 301 Moved Permanently, etc.), cURL will make a new request to the URL specified in the Location header of the response.

If you set CURLOPT_FOLLOWLOCATION to false (or 0), cURL will not follow redirects. In this case, you'll receive the response for the redirect response (3xx status) rather than the final destination.

Quoting from docs:

CURLOPT_FOLLOWLOCATION TRUE to follow any "Location: " header that the server sends as part of the HTTP header (note this is recursive, PHP will follow as many "Location: " headers that it is sent, unless CURLOPT_MAXREDIRS is set).

When you request a URL, you can sometimes be redirected to some other URL. In PHP it'd be done with:

header('Location: http://example.com/');

This directive instructs CURL to load that URL instead of the original one, as HTTP mandates. There's normally no good reason to disable it.

It tells CURL to ignore 30x HTTP redirect headers or not. If set to true, "Location: <someurl>" HTTP headers in the response will cause CURL to issue another request to the location specified in this header.
