Hi, many of my sites generates a web.log of 800Mb every month. How can i reduce this size? Is any bad function?

Thank's

If your sites have so many accesses, then you can't do anything about it. But you can delete old logs (from previous months) that you don't need anymore.

Any script to automatic delete the logs X time old?
I think is a usefull feacture.

Thanks for your help :)

You can do this with the find command. There's an example script in this tutorial: http://www.howtoforge.com/back_up_mysql_dbs_without_interruptions
