Right. There _IS_ a legitimate use of cookies. Likewise deleting the amazon cookies means that the the partial orders in my shopping cart disappear. Neither is a big deal, I guess, but annoying. Fortunately there are solutions to this problem- a number of people have written programs that can be used to seletively accept cookies. I wrote one, "Junkbuster" is another, and I'm sure that a 10 minute web search would find more. Mine and Junkbuster can also be used to block ad URLs, which is pretty handy for just about any web site these days-- saves on download time and you don't have to ignore the spinning flaming logos. www.lne.com/ericm/cookie_jar One other thing on the doubleclick optout page -- after you get your cookie "fixed", it has a button that says "Close Window". Clicking on this starts a java applet on my machine which crashes Netscape -- anybody know what this is about? Obviously, "close window" is a trojan something -- they don't need to run an applet on my machine to close a window on their website. cookie_jar will selectively block stuff enclosed in SCRIPT tags but there's a lot of other ways to send javascript/activeX.

So possibly the "opt-out" is just a scam, and they track under another name, so you won't know to delete those cookies? possible. I noticed that imigis.com and avenuea.com get used on sites that use doubleclick, now that I put that into the DNS killfile. it looks up a lot of ad.doubleclick.net (rotates between that and the site I'm viewing very quickly, since both are in the dns cache), then turns to imigis.com the interesting part is that even though the HTML source points to a file on doubleclick.net, there IS some image there. no hint of imigis.com anywhere on the whole page, even though I positively saw it being looked up in the status line. anyone knows what's going on here? just the usual paranoia, or is doubleclick really up to something?

Re: Opt-Out of DoubleClick
Yeah, I know how to do that. But it has the same problem that it does in using grep to check your system logs every day -- it misses stuff you haven't thought of. Finding a way to defeat the doubleclicks would be better, if you could keep up with all their various personas and nyms. But perhaps you're right, maybe it's too difficult to keep up with, and better to just kill all cookies except the few known to have value.

I'd rather "opt-out" by adding them to ipchains.
% grep doubleclick /etc/named.conf
zone "doubleclick.com" { type master; file "emptysoa"; };
zone "doubleclick.net" { type master; file "emptysoa"; };
% cat emptysoa
$TTL 0
@ SOA localhost. root.localhost. ( 1 1s 1s 7d 0s )
@ NS localhost.
% ping ads.doubleclick.net
ping: Cannot resolve "ads.doubleclick.net" (Unknown host)
so...what's the problem? think of it like blocking spam.
