We want to get an idea of the amount of Range requests we currently receive as a percentage of the total.
The data-gathering procedure should only include meaningful Range requests. For example, Range: bytes=0- is not a particularly interesting one, as it ends up requesting the whole file. Same goes for Range: bytes=0-N for a file of length N+1.
Finally, we want to find out what percentage of those are high-range requests beyond some bytes cutoff (say 32M).
