/*
It does not make sense to store multiple key-value pairs into one cookie, because by
definition a cookie represents one key-value pair.
I believe you don't understand well how document.cookie works.
It is not a standard JS string: when you set it, the cookie definition it contains
is appended to the list of existing cookies. That is, you cannot set two cookies at
the same time using this API.
You have two solutions:*/
document.cookie = "myCookie=myValue";
document.cookie = "myOtherCookie=myOtherValue";
//Store a single cookie with a custom serialization of your complex data, for example JSON:
document.cookie = "myCookie=" + JSON.stringify({foo: 'bar', baz: 'poo'});
