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.
