This looks like the proper approach as far as the CURLOPT_WRITEFUNCTION option
goes. However, many sites do for example redirect the client on the response,
so using followlocation might give you the result you want (and/or it requires
cookies or other stuff you don't pass on in your request). You could use
LiveHTTPHeaders to figure out the differences between the libcurl's and
Firefox's requests and responses.
