bq. Right now there's no way of knowing the txid of the downloaded image. I
think the best solution is to add a header like:
I added a Content-Disposition header in all cases of downloading an fsimage or
edits file so that third-party HTTP requests will work, and added a
Hadoop-specific header in the case of fetching the latest image, so as to avoid
having to parse the Content-Disposition header.
