I was wondering the same exact thing today:

">Could you help me and explain how session cookies work in curl please ?"

I dont understand PHP.net's explination:

"CURLOPT_COOKIESESSION TRUE to mark this as a new cookie "session". It will
force libcurl to ignore all cookies it is about to load that are "session
cookies" from the previous session. By default, libcurl always stores and
loads all cookies, independent if they are session cookies are not. Session
cookies are cookies without expiry date and they are meant to be alive and
existing for this "session" only."

I am also a noob with no experience using libcurl to log in / out of a
session based website.

response is much appreciated.
