Compressing Apache logs

The apache logs that build up with ISPC are inordinately large, so I'd like to gzip the old ones. I'd run a script to do so every couple of weeks. My script-fu, however, is not strong enough to figure out how to find exactly what files I'm looking for, pipe them to gzip properly, and still be confident that I won't break it.

Does anyone have a script for this that they could share?

 

I mean the web.log files that accumulate in the directories of my clients.

 

Have a look at this PHP code at the end of /root/ispconfig/scripts/shell/webalizer.php:

PHP:
