But then again, I did not say that.  Note the qualifier "without the user's
consent".

I would have no problem with excite.com having a link `go to webcrawler.com
and take your excite preferences with you'.  I would gladly use such a link.

And a preferences-in-the-webcrawler-URL scheme would not need to screw up
caching, bookmarking, etc etc at all: simply have webcrawler copy the
preferences back to a cookie and redirect to a plain URL:

 [following the `go to...' link on excite.com leads to:]

   |
   V

 GET /import-prefs/textonly&wacky HTTP/1.0
 Host: www.webcrawler.com
 Referer: http://www.excite.com/blah

   |
   V

 HTTP/1.0 302 See other
 Set-Cookie: prefs=textonly&wacky;path=/
 Location: http://www.webcrawler.com/

   |
   V

 GET / HTTP/1.0
 Host: www.webcrawler.com
 Cookie: prefs=textonly&wacky

See?  The only thing you need is a user deciding to click the link.
