First, you can still use libcurl's ability to extract the time of the document
and still get the headers you want.

Then, libcurl also offers CURLINFO_CONTENT_LENGTH_DOWNLOAD for
curl_easy_getinfo() (or even the progress callback) so you won't need to do
any parsing of your own for that header either.
