PicBot (something like that) crawled one of my sites recently and merrily ignored all the dynamic stuff in the URL's. I think Google can do that now, too.

no-cache tags and [setmimeheader] tags are used in an effort to prevent caching.In my personal experience, some users think of a computer the same way they think of a TV: neither requires any maintenance or updating.They don't read geek news, so they have no idea that their browser is 2-3 versions out of date or why 12 Megs of RAM simply isn't enough anymore.Glenn------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
