Re: Sorry for interrupting again :-(

I don't think I can make it much clearer. You can't use the Polygraph
logs from cacheoffs as a source of URLs to run through your cache. If
you understood the other sentences surrounding that one, then you got my
meaning already (I repeated the concept several times, since I could
tell you were having trouble grasping what I was talking about).
