This data is culled from our daily summary data files. In those files, we classify every request into an object type, currently based on these rules. Note, these rules changed significantly in mid October 1996. Because of this change, some of the graphs show discontinuities at that time. Only a subset of all object types are shown in these graphs to make them easier to view.
This data MAY NOT be representative of all Internet traffic. Usually, our cache clients are configured to NOT forward certain requests (CGI, POST) to our caches.
You may also access the raw data used to generate these graphs. The fields in each data file are: time, total counts, total bytes, relative counts, relative bytes, mean file size. Note, ideally we would have median object sizes instead of mean, but that requires having the size for every request instead of the totals available from our short daily summary data files.
