That's with a full GET request with the whole file, my code is sending a HEAD request which doesn't download the whole file but just the headers.
I tried it in readyState 3 just in case and it throws a very descriptive "Unspecified error" 
It seems the response (getResponseHeader, responseText etc.) can't be accessed until the request is complete?

3 (Receiving) Some data has been received. responseText is not available. responseBody is not available.
4 (Loaded) All the data has been received. responseText is available. responseBody is available.
The remarks also provide a couple of possibilities that could be used, I shall experiment further
