In the meantime, I managed to find this, which I thought worth sharing in spite 
of the bad English grammar:

AB's Useful Box - Apache for Win32 Log file Rotation

So you have finished installing Apache for Win32, one of the best web servers 
you can get on your WinNT / Win2K / WinXP machine, but find that it's log files, 
access.log and error.log just keep on growing !

Well fear not, it is possible to manage those log files, and automate the 
process with out to much grief.

The following batch file, the was written and tested on WinXP, but should just 
as well on WinNT and Win2K, should:

     * store the current date and time into a varible
     * stop the Apache web service
     * move the log files, using the date/time as unique filename
     * restart the Apache web service
     * if prefered, use a command line zip utility to zip the logs
     * keep only the last "x" logs, and delete old

:: remove temp files
del /Q arclist.dat
del /Q dellist.dat


The command line 7za zip utility is available from

The best method is to just put the 7za.exe file into your system32 folder.

Then it is just a matter of calling the batch file from the windows scheduler. 
On WinNT this is done on the commend line via AT and on WinXP this is done via 
Scheduled Tasks found in the Control Panel.

Some other things that can be done after the files have been moved, but before 
they are zipped, it to produce statistics from the access.log data. For example, 
how many times pages are being visited and from where.
