Can't access a session cookie with a domain and path

Question

I want to know : why i can't access this session cookie that has a domain and path ?

Is there a solution ?

Answer 1

You haven't shown all the data from the cookie inspector, but most session cookies are marked httpOnly which explicitly sets them to be inaccessible to client-side JavaScript.

There is almost never a good reason for client-side JS to access a cookie identifier, so marking them as httpOnly prevents an XSS attack from passing the session ID to an attacker (which would make it much easier to hijack the session).
