Block/allow cookies based on cookie name

[juhiyu]

Hellos, I am not sure if this but I would like to ask if it is possible to block/allow cookies by name?

just an example to help understand:

(1) github.com - has cookie name "logged_in". currently CM+ can block all cookies from a particular site but is it possible to block only cookies with the name "logged_in" on a per site/global basis?
(2) for allow cases - is it possible to allow only a cookie named "logged_in" and block every other cookie from github.com?

At the moment it's not possible, but after adding read-only routine, blocking could be possible in the future.

Actually it's possible simulate blocking cookies by name using read-only feature:
set expiration to read-only and change it to current time + 10 seconds, so when cookie expired, browser will not send such cookies to website, and any attempts by website create new cookie with same name will result in instant expiration, simulating blocking cookie by name.

Good thinking. not try it yet but seems automatic way to do this may make blocking work (CM+ can insert dummy value to cookie before/as cookie is set by site and then set expired date/read-only so browser won't send it and site cannot set it again?) but i have not given it too much thought or testing. one issue i see it will be restricted only to 1 site not multiple sites/global.

method may also be viable for allow cases but I am not sure (CM+ can have certain cookie(s) set by user as allow and automatically use the expiry method to block every other cookie and actively keep searching for cookies and block before they are set by the site?).
