A persistent cookie (x1st) is dropped straight away when a user lands on my site with a unique value (of whatever 'hdflashfafafxx233ddd').
This cookie is used for tracking, but if the user opts out of tracking cookies I need to set this value to 0 - I cannot delete it as this is cookie reset constantly.
I then need to expire x1st with the value of 0 when user opts back in.
//cookie set by server
$.cookie('x1st', 'hdflashfafafxx233ddd', { path: '/', domain: mysite.co.uk });
//changing value of cookie when user opts out
$.cookie('x1st', 0, {path: '/', domain: mysite.co.uk });
//expire cookie when user opts back in
$.cookie('x1st', 0, { expires: -1 , path: '/', domain: mysite.co.uk });
The problem is I am unable to change the value of the x1st cookie to 0
