I thought you could check the apache logs for the filesize, but then I
wasn' sure if it just reported the size of the file or the actual number
of bytes transferred, so I tested it:

We'll test it with the new Counter-Strike patch file:

-rw-rw-r--  1 tonyc  tonyc  20465180 Mar 13 17:08
/usr/home/tonyc/public_www/csv1011.exe

Now, looking at the apache logs:

192.168.1.51 - - [14/Mar/2001:12:14:34 -0600] "GET /~tonyc/csv1011.exe
HTTP/1.1" 200 2949120
192.168.1.51 - - [14/Mar/2001:12:14:53 -0600] "GET /~tonyc/csv1011.exe
HTTP/1.1" 206 7839744
192.168.1.51 - - [14/Mar/2001:12:17:19 -0600] "GET /~tonyc/csv1011.exe
HTTP/1.1" 200 20465180

Comparing the last number to the size of the file on the disk, you can see
that there were two aborted transfers and one complete. You could write a
real quick and dirty Perl script to go through the logs and compare the
file transferred against the total size of it.

Hope that helps.
