Hello,

I want to have code to get content-length without actually reading the data.
the code below works fine for 'http' scheme but does not for 'file' scheme.

------------------
  curl_easy_setopt(dwHandle, CURLOPT_URL, url);
  curl_easy_setopt(dwHandle, CURLOPT_HEADER, 1);
  curl_easy_setopt(dwHandle, CURLOPT_NOBODY, 1);
  curl_easy_setopt(dwHandle, CURLOPT_WRITEFUNCTION, &nullOut);

  curl_easy_perform(dwHandle);
  curl_easy_getinfo(dwHandle, CURLINFO_CONTENT_LENGTH_DOWNLOAD, &dSize);
------------------
it always returns 0 for file.

I have take a look into the code and found that no code
to set the progress.size_dl exists in the code path for NOBODY and HEADER.

I added two lines of code as attached patch, and it looks like works fine.

Is this a bug, or am i missing something?

      return result;
    }
