Transfer of 0 bytes with a 200-OK status means that Google did a Conditional GET, with an If-modified-since HTTP request header, and your server responded with zero bytes because the Last-modified date on the file indicated that Google's cached copy was still current. Therefore, it was unnecessary to transfer the same 'old' content.

The elimination of unnecessary bandwidth and server resource usage is precisely the purpose of the Conditional GET request. You will also see some clients use HEAD requests for the same purpose, although a CGET is more efficient.

In short, don't worry about it. All is well.
