Squid Cache: Version 2.6.STABLE22

I didn't know the none flag worked, guess I was trying the more complex
things with the store log file. I had deleted the swap.state file and it
took forever to rebuild (over night processing, though not bad) but
nothing else bad happened, but I had picked up that it was bad to delete
the file. The version of squid is a little lagging because I need to
upgrade the entire system and haven't had a chance yet, but I also don't
want to port a bad config over to the new build.
