Since I'm running SquidNT there's no native log rotation method. I'm writing a batch file to handle this, but I would like to zip up the archive copies of the log to save space, seeing as how store.log and access.log are 500MB+ each in less than a week. Thing is, I want to run this from the command line, preferably without relying no any 3rd party solutions. I looked at compress.exe in the Windows 2003 Resource Kit, but I'd rather take advantage of the built in ZIP folders if possible... plus I couldn't figure out in three minutes how to uncompress them, and I don't want to rely on people remembering to compress them again after. Anyone know of a built in method I can use to do this?
