Hello,
You have the major parts, especially "HTTP session ID joined with IP and SSL
session ID'. Most web-apps don't do this, but they should.
To that one should add
A) allow only one active login

Subject: How to create (hijacking) secure HTTP sessions?
Hi!
I tried to figure out, how to create HTTP session, that are not so easy
to hijack.
So I think about that mechanisms:
* Using HTTPs
* Randomize HTTP session IDs
* Only create HTTP session ID after login
* HTTP session ID joined with IP and SSL session ID
* Block all session ID usings, that do'nt match IP and SSL session ID
* Set HTTP session timeout
* Expire HTTP session after logout
Is that all? Is there any mechanism, that isn't a good idea?
Bye,
Michael
