Losing session data on logout?

Question

symfony

I open the site
I look at the debug-bar and remember the cookies responsible for the session I
put the goods in the basket (the basket is stored in the session)
I do the login
I look at the debug-bar I see that after the login the value of the cookie has changed
while the basket remains saved
I logout /logout
I look at the debug-bar I see that the value of the cookie has changed again
and the basket is gone
how can I solve the problem of losing the basket?

Read about the session mechanism. Understand why this is happening.
Store the cart in the database. And to drag in session at login.
