Cookies not read correctly in asp.net core

Question

Browser confirms that both curvlist and guestuser cookies exist. However When I get the guestuser it has the correct value:

string Guest = Request.Cookies["guestuser"]; 

but the cookie curvlist is empty:

The only difference is that guestuser is created in server side, but curvlist created by javascript. But it has nothing to to with reading the cookies

Answer 1

Experimenting different values for the cookie, I found out something that is very stupid (correct me if I'm wrong): Apparently cookie name and value is separated by comma so having commas in the value would lead loss of the rest of the value after comma (in my case starting with comma would lead to empty value). I changed the separator in cookie to $ instead of , and now I'm getting the correct value.

But why Asp.net reads cookies this way? (Note that there was no problem when reading cookies with comma separated values in the javascript .

Answer 2
