Introduce "persistent" and "immutable" cookies
Stefan Kanthak
Opera should introduce a flag/setting in its cookie manager
to allow "persistent" and "immutable" cookies:
- "persistent"/"immutable" cookies are never deleted, even
when the user requests to clear ALL cookies;
- "persistent" cookies may be changed/written to by the
creating site;
- "immutable" cookies may not be changed/written to.
Rationale: retain user settings stored by websites like
<http://www.networkadvertising.org/managing/opt_out.asp> or
<http://support.microsoft.com/common/international.aspx>
but still allow to clear all (other) cookies.

Cookies are already persistent - a better term would be permanent.

Specifically they don't expire, and can't be deleted by the site. They can
be deleted individually, and with delete user data - when the user selects
delete permanent cookies option in the delete user data dialog.
I would also say that immutable cookies are treated as normal - however
you can set a cookie to be both permanent and immutable.

Also use for sites that has a short life on the login cookie so you have
to keep logging in.
