I am a bit confused now.

For example, using the Opera browser, a user can check a cookie value. I
understand that this value is used to identify a user, ie I can read it. But
other people, on LAN or internet, cannot read it because when I send data,
the data is enrcypted via https.

I suppose the cookie value is the Session ID.
