Suppose someone cancels mid-way, or an error occurs, then there is a log to show that file transfer was not complete.

You probably need a script to proxy the downloads - channel all downloads through this proxy script. in the script you ll need to do something like this : 1 - get the size of the requested file 2 - read the file and write the contents of the file as binary into the output stream 3 - when the script completes compare the output no. of bytes with the original byte size (from step 1 ) 4 - write success / failure of the download to a log file depending on wether the comparison was equal or not in step 3

Hi, Yes, it logs those requests, but you need to use mod_logio http://httpd.apache.org/docs/2.2/mod/mod_logio.html to know the actual bytes sent, else it will show the total amount of bytes of the file. And to know which have failed you'd have to either: 1. use the %X format modifier and use a custom log format 2. compare the actual bytes sent against the file' sizes On Tue, Sep 22, 2009 at 10:53 AM, Arthur Buliva <abuliva@mobileplanet.co.ke> wrote:

Is there a way to configure either Apache or Tomcat web servers so as for it to display how much data was transferred in a given session?

Any idea(s)?
