Session cookies = cookies?

Question

I wonder if cookies are the same as session cookies?

Answer 1

A cookie is a cookie.

"Session cookie" can refer to one of two things:

• A cookie with unspecified timeout, which will be discarded as soon as the browser is closed. I.e. the browser will only retain it for the current "browsing session."
• A cookie containing a session id.

Sometimes it means both. It's not a very well defined term.

As such, the correct description would be session cookie ⊆ cookie,
instead of session cookie = cookie. ;o)
