I'm sure most of you know about Vadim's Apache stats project for 
tracking download statistics for the verious Apache projects:

http://people.apache.org/~vgritsenko/stats/index.html

A fun little project but exceedingly difficult (not to mention time 
consuming) for Vadim to dig into the details of each project in order to 
present project stats with finer details.

Just out of curiosity, I did some Ruby hacking to modify Vadim's apache 
log mining script to filter out Geronimo project data with finer 
resolution.  Here are the results:

http://people.apache.org/~stoddard/stats/data/

I'll not bother commenting or summarizing on the different results 
because it's exciting in exactly the same way as watching paint dry.

The one item that might need a bit of explaining is the reference to 
'206W', so I'll cover that briefly...  A 'successful' reply to an HTTP 
Range request is a status '206'  response (see RFC 2616 if you want to 
know about range requests).   So the '206' in 206W refers to a 
successful reply to a Range request.  The 'W' means 'weighted'.... more 
on 'W' in a bit.

An example... if the size of a file to download is 100M, a client can 
make 10 range requests, each requesting a different 10MB segment of the 
file.  There are various reasons why a client might issue a range 
request (PDF, acrobat and similar viewers, high bandwidth but very low 
latency connections between the server and client and so forth. reason 
is not important to this explanation... ).  Each of the 10 Range 
requests will create a 206 reply entry in the web server's log file.  
So... if we are counting downloads of that 100MB file, it would be 
incorrect to count each 206 reply as a download.  The 'w', which stand 
for weighted... in this case, the '206W' download count would be '1'.  
The 10 206 replies are equivalent to 1 download of the 100 MB file.

fyi...
