And I am not sure if it is possible to anyhow reliably distinguish the two urls. In the case of obtaining pre-compressed file from my sample apache server the only difference in the http response header is that it gets \"compound\" ETag: compare ETag: \"3acb0e-17b38-4dd5343744660\" (for directly asking zeros100.gz) vs \"3acb0e-17b38-4dd5343744660;4dd5344e1537e\" (requesting zeros100) where portion past \";\" I guess signals the caching tag for gzipping, but not exactly sure on that since it seems to be not a part of standard. Also for zeros100 I am getting \"TCN: choice\"... once again not sure if that is any how reliably indicative for my purpose. So I guess there is no good way ATM via Content-Type request. """]]
