Sam, last things first:  A server doesn't look for anything; it *asks*
your browser to provide something to it.  If it wants a cookie, it asks
the browser to send "a cookie for what we're doing now" which starts
with" or some such.  The browser searches its cookie file and if/when it
finds "a cookie for what we're doing now" [i.e. one that matches
paramenters sent by foreign server], that cookie is sent as requested.

Some sites can use "spyware" to track you because you never *leave* that
site.  You may *think* you've left the site, but you haven't.  It's like
some sites that have frames, and when you go to a foreign link the
original site's menu/ID/framework is still there ...  the "spy sites"
have frames you don't see.  I now believe that AltaVista is working on
that type of setup.  I once visited AltaVista for a short period and
then went somewhere else; when I got to somewhere it had a javascript
that Arachne couldn't [of course] handle, and instead of the error
message I got an AltaVista page with info about javascripts!

NBCi uses this invisible framework too, if I guess correctly.  That is
the only way you could "find a word, click, and get it explained"
"anywhere" ...

Now dozerware users don't even know what "frames" means, so I'm sure
they think all that crap [including the stock ticker which 'goes
everywhere with you'] is just one more "feature" of dozerware itself.

If you think you've gotten entangled in a "spy site" it is fairly easy
to cure with arachne.  I just can't remember off hand how I do it, but I
think a "clear cache" which then reloads just the current page should do
the trick.
