I simply don't understand how this keeps coming up. Anyone
who's spent even a brief period of time dealing with state
on any enterprise application knows the pitfalls of this.

Yet another reason we should be focusing our efforts on
documenting proper state and session management.

If basic issues like IP tracking are still misunderstood by
people on *this* list...what's the rest of the world like?

While it may be argued that the "session riding" whitepaper
stimulated this conversation, the power-point friendly orientation
of the web application security industry appears to have
created an environment where one is rewarded more for new
"vulnerability finds" (e.g.-"Session Castling") than for
creating thorough standards and practice documentation.

If I am wrong, someone stand up and shout "I'll take Uninformed
Opinions for $1000, please", point me to resources I have
missed, and I will shutup.
