Hello, everyone!

I wonder why the data logged in connection.log and in http.log differ so much. After some research I found out that the true size of a downloaded file is shown in http.log. Here's an example:

http.log
192.168.x.x - someone<_at_>ourdomain.local [14/Sep/2006:10:06:45 +0300] "POST http://dl4l3.rapidshare.de/files/15594381/3206916076/somefil e.rar HTTP/1.1" 200 9000000

connection.log
[14/Sep/2006 10:08:46] [ID] 468332 [Rule] NAT [Service] HTTP [User] someone [Connection] TCP C145:1899 -> 62.67.57.9:80 [Duration] 474 sec [Bytes] 183793/9403415/9587208 [Packets] 4331/10079/14410

The size of a downloaded file is 9000000 sharp, which is shown in the http.log as I've said before. As far as I understand the numbers shown in connection.log in [Bytes] section consider the sum of IP packets. I just wonder why there're three of them.

And there's the second problem. An example from http.log:

192.168.x.x - someone<_at_>ourdomain.local [13/Sep/2006:14:50:23 +0300] "GET http://www.preplogic.com/products/exams/download/528/setup.e xe HTTP/1.1" 206 637455

The real file size is 5234875. Why KWF counted it that wrong?

Thank you very much in advance for your explanations.

It counts bytes transferred In/Out/Total sum.

KWF counts it correctly. 206 response is a partial download. Your client is downloading the file in several pieces. This is one of pieces.
